Question

Describe an addition problem that you may need to regroup hundredths to solve

Answer 1

Lets consider a basic problem of addition of three decimal numbers which includes hundredths .

`3.16+4.12+2.01`

When we add all the three decimal numbers , we regroup all the digits according to their place value (start from left) and then add them.

Now,

Addition of digits on their hundredths place=
`6+2+1=9`

Addition of digits on their tenths place =
`1+1+0=1`

Addition of digits on unit place =
`3+4+2=9`

Arrange the answer according to their corresponding place, we get 18.19

Hence,
`3.16+4.12+2.01=9.19`
