Write a decimal subtraction problem that requires regrouping to solve. then solve the problem.

0.31 - 0.15

Step-by-step explanation:

Regrouping in math is used in the process of changing groups of to make adding and subtracting easier.

That is, if we have a problem,

0.31 - 0.15

Since, 1 < 5 so, we can not get hundredth place digit directly.

Thus, we will borrow one digit from the tenth place, and after borrowing the number is 11, ∵ 11 - 5 = 6,

So, the hundredth place digit of the resultant number is 6,

Now, after borrowing 1 from tenth place, new tenth place digit is 2 and 2 - 1 = 1,

So, the tenth place digit of the resultant number is 1.

Again, 0 - 0 = 0,

So, the ones place digit of the resultant number is 0.

Hence, the answer is 0.16.

That is, 0.31 - 0.15 = 0.16
