Question

How to write two different pairs of decimals whose sums are 14.1. One pair should involve regrouping

Answer 1

To solve, first let’s define regrouping:
=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.

So let us have the non-regrouping decimal number: 
=> 8.4
Next, the other regrouping decimal 
=> 5.7

So now let us show how it becomes 14.1:
  8.4
+5.7
14.1

Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
Thus, the answer is 14.1
