Question

Which of the following is the difference of 35.6 and 7.43? O A 27.17 O B. 2723 OC. 28.17 O D. 28.23

Answer 1

To find the difference between the numbers, we need to substract 7.43 from 35.6.

First we align out values with the decimal point:

We add a zero to 35.6 to have the same number of decimals as 7.43

Now we start the substraction by borrowing one from the 4:

We have that 10-3 is 7, we continue with 6-5 (the number 5 is because of 4 and 1 we added is 5)

In this step, we also lower the decimal point.

we finish the substraction by also borrowing one for the 5 to become a 15, and we give it back just bellow the 3:

This is because 15-7 is equal to 8, and 3-1 is equal to 2
