Which number is 7 times more than itself 27? 5

It can be understood that seven times a number minus itself is 27, that is, 6 times is equal to 27, so this number is 9 2

Hello, 7 unknowns equals unknowns plus 27, so unknowns equals 27/6

Suppose this number is x, according to the meaning of the question, we can get 7x-x=27, that is, 6x=27, and solve x=27 6=, so this number is.

Let this number be x, and 7 times this number is 7x

7x-x=27 6x=27 x=

We can start by setting this number to x, and then we can set the equation.

7x=x+27

i.e. 6x=27

i.e. x=27 6=

This number is 9 2

Validation: 9 2 7 times is 63 2, 63 2-9 2 54 2 27

The process of solving the problem is as follows:

The answer is 27 (7-1)=

The end result is.

9。More than 27 is 3 times it, so this number is 27 3

What is the sum of 7 5's? Analysis: 7 times of 5, the formula 5 7 also represents the sum of 7 5s; 5x7=5+5+5+5+5+5+5+5+5 represents the sum of 7 5s.

Extended information: Multiplication is a simple addition operation, and division is a simple subtraction operation. Subtraction and addition are inverse operations, and division and multiplication are inverse operations.

Integer addition and subtraction algorithm: 1Align the same numbers; 2.

From a single digit; 3. When the ten digits are reached in the addition, turn to the high position; When subtraction is not enough, take a step back by 1 and subtract again when this number is added by 10. The properties of the addition operation can be obtained from the commutative and associative properties of addition: when multiple additions are added, the positions of the additions can be arbitrarily exchanged; Or add a few additions and then add the others, and their sum is constant.

For example: 34 + 72 + 66 + 28 = (34 + 66) + (72 + 28) = 200.

27 (7 1) 9 2 , so that this number is.

You can set this number to x, 7x-x=27Then solve!

What is this number? Hello, this number is 9. 7 times more than 4 times a number is 27, and that number of 27 is actually 3 times his number, so this number is 27 3 = 9.

Multiples of 27 have and so on.

The last two digits of a number are multiples of 27, and this number is a multiple of 27. The number is infinite, so there are infinite multiples of 27.

Multiplier nature: Multiples of 2.

At the end of a number is an even number (0,2,4,6,8), and this number is a multiple of 2.

For example, the end of 6 is a multiple of 2. 3776÷2=1888。

Multiples of 3. The sum of the digits of a number is a multiple of 3, and this number is a multiple of 3.

4926。(4+9+2+6) 3=7, which is a multiple of 3. 4926÷3=1642。

Multiples of 4. The last two digits of a number are multiples of 4, and this number is a multiple of 4.

is a multiple of 4. 2356÷4=589。

There are an infinite number of them, and you can hold a computer and put 27x x x4 and so on in multiples of 27, until your hands are sore, and you can't count them when you get old.

There are countless of them. x2 x3....It is.

Endless. Factors are there.

Multiples of 27 have and so on.

The last two digits of a number are multiples of 27, and this number is a multiple of 27. The number is infinite, so there are infinite multiples of 27.

Multiplier is a mathematical term that refers to the product of a number and an integer. For two numbers a and b, if there is an integer n such that b = na, then b is a multiple of a; If a is not zero, it means that b a is an integer, and its division is divisible with no remainder. Multiples of 2, also known as even.

If a and b are integers, and b is a multiple of a, then a is a factor of b.

Features of some digital multiples:

1) Multiples of 2.

At the end of a number is an even number (0,2,4,6,8), and this number is a multiple of 2.

2) Multiples of 3.

The sum of the digits of a number is a multiple of 3, and this number is a multiple of 3.

3) Multiples of 4.

The last two digits of a number are multiples of 4, and this number is a multiple of 4.

4) Multiples of 5.

If a number ends with 0 or 5, this number is a multiple of 5.

Divisor, also known as factor. The quotient of the integer a divided by the integer b(b≠0) is exactly an integer without a remainder, and we say that a is divisible by b, or b is divisible by a. Example:

Within the range of natural numbers (0 and positive integers), any positive integer is a divisor of 0.

The positive divisor of 4 is .

The positive divisor of 6 is .

The positive divisor of 10 is .

The positive divisor of 12 is .

The positive divisor of 15 is .

A multiple of 27 and 7 is a multiple of 27 and a multiple of 7 at the same time. We can find that they don't have the least common multiple to determine such a number.

Multiples of 27: 27, 54, 81, 108, 135,

Multiples of 7: 7, 14, 21, 28, 35,

As you can see from the list above, the least common multiple of 27 and 7 is 27 7 = 189.

Therefore, the multiples of 27 and jujube 7 are multiples of all 189, i.e. 189, 378, 567, .Wait a minute.

Multiples of 27 are 27, 54, 81, 108, 135, 162,

Multiples of 7 are 7, 14, 21, 28, 35, 42, .,

The common multiple of 27 and 7 is Wang Ji 27, 54, 81, 108, 135,7, 14, 21, 28, 35, 42, .27, 54, 81, 108, 135, 162, .

The two numbers 27 and Zhongbi 7 are coprimitive.

27x7＝189

27 and 7 Bizi has a minimum of 189

27 is not a multiple of seven, and a multiple of seven is a difference of 21 or 28.

These inflated numbers can be found in the multiplication formula, withered with three seven twenty-one, four seven twenty-eight. There is no such thing as a multiple of seven, such as 27.

The title should be wrong, 27 is not a multiple of 7.

Summary. Hello dear, the number greater than 7 42 is 7 times 7 7 7-7 = 42 is 7 times greater than 7 is 7 times the number of 7.

Hello dear, the number greater than 7 42 is 7 times 7 times 7 7-7=42 The solution column should be 7 7 = 49-7 = 42

According to the calculation of this number is, because a number of 7 times more than itself, then it can be used.

7 times more than a number is itself.

7 times is so much more than him, which means that Danchai has 6 times more molded limbs.

You'll get this number.

7 times the number of a number is more than the branch itself, and the number of this letter is.

Analysis: This number is 1 times that of its own fierce match, then, this number is:

This problem can be done using a univariate one-time function.

Let this number be x, then the number of seven calls is 7x

According to this and pure conditions, it can be discussed with caution.

6x=x＝

7 times more than a number itself, what is this number, so the number is.

Assuming this number is x, then 7x-x=

The solution is x=

Summary. Dear, the calculation process is as follows: this number is.

Dear, the calculation process is as follows: this number is.

Dear, are you a student or a parent?

Parents! I don't know what is right or wrong when I teach with equations! I just asked <><

Dear, the child is in the fifth grade.

Fourth grade. Oh! In the fourth grade, I haven't been exposed to equations yet, so I can't use them to solve problems!

Are teachers engaged in math?

How to add you!

Pro, click on the avatar, pay attention to it, and consult it.

I would like to ask how I can improve the writing accuracy of my calculations!

I'm following you! Kids are all calculating questions in exams! The application questions are all miscalculated! Speechless! <>

Dear, you can substitute the calculation results into the original question, take the calculation results as known conditions, and see if they are consistent with the conditions given, and you will know that you are not doing the right thing.

Summary. 7x4+67=28+67=95。

7x4+67=28+67=95。

Dear, the answer is 95 Oh, please check.
