Question

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

Answer 1

`3+(-7)+(2)/(5)+(-(1)/(5))`

Explanation:

We are given that an expression

`3(2)/(5)+(-7(1)/(5))`

We have to find the expression which shows the sum of integer and fractional parts.

The given expression can be written as

`3+(2)/(5)+(-7-(1)/(5))`

Now, adding integers

`(3+(-7)+(2)/(5)+(-(1)/(5))`

Now, adding fraction parts we get

`3+(-7)+((2)/(5)+(-(1)/(5)))`

Hence, the expression which shows the given expression as a sum of integers and fractional parts is given by

`3+(-7)+(2)/(5)+(-(1)/(5))`
