Answer:
The answer is provided as a whole explanation
Step-by-step explanation:
Regrouping is the presentation of a number or decimal with its number groups. For example, we can represent 0.25 in this way:
0.25 = 0.2 + 0.05
0.25 = 2 tenth + 5 hundredth
We can also write 0.25 as:
0.25 = 0.1 + 0.15
0.25 = 1 tenth + 15 hundredth
Regrouping is handy to simplify a mathematical calculation since we know how many tenth or hundredth we have got in this case.
