Which expression shows 3 2/5+(7 1/5) as a sum of integer and fractional parts?

Answer:
[tex]3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]
Step-by-step explanation:
We are given that an expression
[tex]3\frac{2}{5}+(-7\frac{1}{5})[/tex]
We have to find the expression which shows the sum of integer and fractional parts.
The given expression can be written as
[tex]3+\frac{2}{5}+(-7-\frac{1}{5})[/tex]
Now, adding integers
[tex](3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]
Now, adding fraction parts we get
[tex]3+(-7)+(\frac{2}{5}+(-\frac{1}{5}))[/tex]
Hence, the expression which shows the given expression as a sum of integers and fractional parts is given by
[tex]3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]
