How do you list the division equation for 420 30?

1.When writing the division vertical, write the vertical division sign first.

2.Then put the dividend.

and the divisor, which are written on the inside and left side of the divisor.

3.The quotient is written above the division sign and should be aligned with the unit digit of the dividend.

4.Then write the product of the quotient and the divisor below the dividend (aligned with the same digits), as shown below.

Vertical parsing step 420 30

Problem solving idea: the dividend from the high position of each digit of the divisor to the divisor operation, each time the calculated quotient is retained, the remainder is added to the next digit for operation, in this order the dividend is calculated so the digits, the obtained quotient is combined in order, and the remainder is the result of the last operation.

Problem solving: Step 1: 42 30=1 The remainder is: 12Step 2: 120 30=4 The remainder is: 0

According to the above calculation, the result quotient of the combination of calculation steps is 14

Check: 14 30 = 420

Extended data - > calculation process: first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier by each digit from the last digit to each digit in turn, and finally add up the calculated result as the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiplier first, and finally the product is reduced by the corresponding multiple;

Problem solving process: Step 1: 0 14=0

Step 2: 3 14 = 420

According to the above calculations, the sum is 420

Hello! 903 divided by 3 equals 301, the mathematical formula is 903 3 = 301, and the division vertical operation is shown in the figure below.

Vertical, refers to the change of each transition number from the previous transition number, the single digit of the previous transition number multiplied by 2, if you need to carry the digit, then advance to the front by 1, and then the single digit rises by 10 digits, and so on, and the single digit is filled with a new operation number.

For example, 42 is divided by 7, starting from 4 divided by high to low. When the division method is calculated vertically, it starts to divide from the highest digit, for example: 42 is divided from the highest ten digit 4; If you can't get rid of it, such as:

4 cannot be divided by 7, so divide by combining the highest digit and the next digit into a number until you can divide by the divisor; For example, if 42 is divided by 7 and 4 cannot be divided by 7, 4 and 2 are combined into a number 42 to divide 7, and the quotient is 6.

Calculate the hundred and ten digits first, 5 7 = 35 is obviously not appropriate, then use 4 7 = 28, so the ten digits are 4.

34 28 = 6, 6 in the 10th place, 1 in the single place. Using 61 7=, rounding up to the nearest unit is approximately equal to.

Use addition to unify the results. 40+

How do you list the division equation for 207 46?

The vertical calculation is as follows:

Answer: 207 46. Write the divisor 207, then write the divisor, then write the divisor 46 from the divisor, then calculate the quotient, and write the quotient above the divide. Column Equation:

The division equation for 64 40 is as follows:

4 0 丿 6 4

Calculation formula.

Vertical formula. When writing the division vertical, write the vertical division sign first. Then write the dividend and the divisor on the inside and left of the divisor, respectivelyThe quotient is written above the division sign and should be aligned with the unit digit of the dividend. Finally, write the product of the quotient and the divisor below the dividend (aligned with the same digits).

Vertical division calculation steps.

Step 1 4 When dividing is calculated vertically, divide from the highest digit of the dividend, if it cannot be divided, then use the highest digit and the next digit to form a number and divide until it can be divided by the divisor.

Step 2 4 Vertical division calculation process, example: 42 divided by 7 from high to low, 42 is divided from the highest ten;4 cannot be divided by 7, so divide by combining the highest digit and the next digit into a number until you can divide by the divisor;42 divided by 7 in 4 cannot be divided by 7, so 4 and 2 are combined into a number 42 to divide 7, and the quotient is 6.

Step 3 4 When dividing is calculated vertically, divide from the highest digit and align the number of digits in the vertical column.

Step 4 4 divides 75 by 5 column vertical as an example, first divide the highest digit of the dividend by 7 in the tenth digit by 5, the quotient is 1 and the remainder is 2, and then use 2 and the single digit of the dividend 5 to synthesize 25 divided by 5, and the quotient is 5, so the final result of the vertical is 15.
