Write a decimal addition problem that requires regrouping the hundredths. explain how you know you will need to regroup

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.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
