Divisor The problem of the dividend, the divisor and the dividend

Dividend Divisor = quotient .........Remainder.

Dividend = Divisor Quotient + Remainder.

Sum = dividend + divisor + quotient + remainder.

and 2 remainders are included, one is the remainder that is added directly, and the other is the remainder contained in the dividend.

First subtract these 2 remainders: 464-2 31=402 At this point, the dividend remains: the divisor quotient.

and there are 402 left, including: divisor quotient, divisor, quotient.

The quotient is known, then subtract the quotient from 402 to get:

This 390 is the divisor quotient plus the divisor.

That is, (quotient + 1) times of the divisor.

So the divisor: 390 (12+1)=30

To sum it up: divisor = (and -2 remainder - quotient) (quotient + 1) This can be remembered as a formula...

But in this question, there is a mistake in principle, the divisor is 30, the remainder is 31, and the remainder is greater than the divisor?!!

One wrong question!!

The addition of the divisor and the dividend is 221, and the divisor is x, and the dividend is 221-x.

Column equations are very simple, and you don't need to use your brain. Let the divisor x and the dividend y. So there is: 12x + 31=y; x+y+12+31=464 Simple binary equations can be solved without even a matrix

However, it seems that the question is wrong

In division, the number after the division sign is called the divisor, and the number before the division sign is called the dividend.

In the division equation, the first number, which is the number before the division sign, is called the dividend, the second number, which is the number after the division sign, is called the divisor, and the third number (the result of division), which is the number to the right of the equal sign, is called the quotient.

Knowing the product of two factors and one of the factors, the operation of finding the other factor is called division. Dividend Divisor = Quotient, Dividend Quotient = Divisor, Quotient x Divisor = Dividend.

Dividend Divisor = quotient .........

Dividend quotient = divisor.

Divisor quotient = dividend.

Divisor = (Dividend - Remainder) quotient.

Quotient = (Dividend - Remainder) Divisor.

You're right. 1 is the dividend, and 2 is the divisor. Because 1 is the number that is divided, but my elementary school foundation is also very poor.

Any number whose divisor must not be less than 3, and the dividend being a number that is 3 more than 4 times the divisor.

In the case where both the divisor and the dividend are positive, when the divisor is less than 1 and greater than 0, the quotient is definitely greater than the dividend, and when the divisor is greater than 1, the quotient is definitely smaller than the dividend. There are also cases where both the divisor and the dividend are negative; When the divisor is positive and the dividend is negative; a situation where the divisor is negative and the dividend is positive; Analyze it yourself.

The divisor can be any number that is not 0, and the dividend is a number that is 3 times more than 4 times the divisor.

Dividend: The dividend is the numerator of the fraction.

Because it is divided (e.g., half, that is, 1 is divided into 2 parts), the one before the division is called the dividend.

It should be understood that 10 is divided by 3, then 10 is divided; 10 is divided by 3, then 3 is the divisor.

You should understand it this way: 10 I said that I was doing well, but I had to divide me into three equal parts, and I was passive. Hehe. 10 is divided into 3 parts.

It's also very simple to understand:

For example, 10-3, where 10 is subtracted by 3 and 7 remains, 3 is subtracted and 10 is subtracted.

So it's not hard to understand the divisor:

10/3=？], meaning, how much does 10 get by dividing by 3? 3 is the divisor, 10 is divided by 3, 3 is left with 1, and 10 is the dividend

- When I was in elementary school, I was also puzzled by this question.

I wasn't as diligent and inquisitive as you, so I wrote it down: the one in front of the formula is the passive number.

Hehe, I hope it will help you, it is not difficult to learn mathematics after understanding, and it is well memorized.

In division, there are two kinds of relationship between the dividend and the divisor, one is divisible, that is, the dividend divisor = quotient, and this quotient is called the complete quotient; The other is division with remainders, i.e., the dividend divisor = quotient. The remainder (remainder "divisor"), this quotient is called the incomplete quotient, and the remainder problem is divided into two types: congruent and non-congruent.

It is known that two numbers a, b(b≠0), require division by a number q, so that the product of q and b is equal to a, this operation is called division, denoted as a b=q or a b=q, read as a divided by b equals q, or a is equal to q than b, a is called the dividend, b is called the divisor, q is called the quotient of a and b.

The divisor is the number after the divisor sign and is called the divisor.

In the divisor, the number after the division sign is called the divisor, such as: 6 2=3, where the 2 after the division sign is the divisor; The dividend is the number that is divided by another number in the division operation, e.g. 24 8 = 3, where 24 is the dividend.

The calculation method of the division is the method of counting the rolling spike brother:

1. Long division.

Long division, commonly known as long division, is suitable for formal division, decimal division, polynomial division (ie.

factorization) and other more emphasis on the calculation process and the division of quotients, and both multiplication and subtraction are used in the process. According to the multiplication table, two integers can be calculated with a long division (straight division) pen. If the dividend has a fractional part (or a decimal point), it is enough to bring the decimal point down when calculating; If the divisor has a decimal point, shift the divisor to the decimal point of the dividend at the same time, and there is no decimal point from the straight branch to the divisor.

The abacus can also do division operations.

2. Short division.

Short division, commonly known as short division, is suitable for fast division, simultaneous division of multiple integers (so it is often used to find the greatest common factor and least common multiple), binary digit conversion and other divisions that pay more attention to multiple tests and prime factors (multiplication), and most of the processes only need to use the multiplication table of ninety-nine and the multiplication factor of a few integers above 9. <>

In division calculations, the number after the division sign is called the divisor. The dividend is the number that is divided by another number in the division operation, and the formula is the dividend divisor = quotient. I've got you covered with division.

1. Dividend: It is the number that is divided by another number in the division operation.

2. Divisor: In the division equation, the number after the division sign is called the divisor.

6, 38 is divided by 6, so 38 is the dividend, and the division sign is followed by 6, so 6 is the divisor.

5, 40 is divided by 5, so 40 is the dividend, and the division sign is followed by 5, so 5 is the divisor.

12, 70 is divided by 12, so 70 is the dividend, and the division sign is followed by 12, so 12 is the divisor.

Dividend Divisor = quotient .........

Dividend quotient = divisor.

Divisor quotient = dividend.

Divisor = (Dividend - Remainder) Quotient = (Dividend - Remainder) Divisor.

a÷b=c（a≥0，b>0）：

The dividend expands (shrinks) n times, and the quotient expands (shrinks) n times accordingly.

The divisor expands (shrinks) by a factor n, and the quotient shrinks (expands) by a factor of n.

The dividend (except 0) is divided by the number greater than 1, and the quotient is less than the dividend.

The dividend (except 0) is divided by the number less than 1, and the quotient is greater than the dividend.

If we think of division as an equal concept, the dividend is the one that is divided. For example, 8 2 means that 8 is divided into 2 equal parts, 8 is the dividend, and 2 is the divisor.

1.The quotient of the dividend and the divisor multiplied or divided by a non-zero number at the same time does not change;

2.The dividend is enlarged (or reduced) several times, and the divisor remains unchanged, and the quotient expands (or decreases) several times;

3.The dividend remains unchanged, the divisor expands (or shrinks) several times, and the quotient shrinks (or expands) several times;

4.If the dividend is enlarged by a fold and the divisor is reduced by a fold, the quotient is expanded by a b times.
