Answer:

The pairs are: No regrouping: 4.29+4.4 and Regrouping: 5.72+2.97

Step-by-step explanation:

Consider the provided information.

We need to write two different pairs of decimals whose sums are 8.69.

you can take any two number whose sum is 8.69

Let say first number is 4.29 then the second number will be 4.4

We can check this by adding the numbers as shown:

 4.29

+<u>4.4   </u>

 <u>8.69</u>

It is required that one pair should involve regrouping.

You can take any two numbers whose sum is 8.69 after regrouping.

Let say first number is 5.72 then the second number will be 2.97

We can check this by adding the numbers as shown:

 1

 5.72

+<u>2.97</u>

 <u>8.69</u>

Hence, the pairs are: No regrouping: 4.29+4.4 and Regrouping: 5.72+2.97
