Question

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

Answer 1

Solution:

Consider the problem of addition of two or more than two decimal numbers which includes hundredths can be solved by regrouping Hundredths

For example

3.098 + 4.7896+ 5.004

It can be written as

Addition of number on unit place = 3+4+5=12

Addition of number on their tens place =$\frac{0}{10}+\frac{7}{10}+\frac{0}{10}=\frac{7}{10}$=0.7

Addition of number on their Hundredths place=$\frac{9}{100}+\frac{8}{100}+\frac{0}{100}=\frac{17}{100}$=0.17

Addition of number on their Thousandths place=$\frac{8}{1000}+\frac{9}{1000}+\frac{4}{1000}=\frac{21}{1000}$=.021

Number on ten thousandths place can be written as=0.0006

So, Sum = 12 +0.7 +0.17+0.021+0.0006=12.8916

Answer 2

255 plus 367 or 367 plus 288
