Answer:


(4)/(5).

Explanation:

1. Write the expression.


1+(2)/(5) -(6)/(10)

2. Rewrite the fractions with a common denominator.

A common denominator is just a number that can be used as a denominator all fractions when we convert them through multiplications. A common denominator is usually found just by multiplying all denominators of all fractions. In this case, we don't need to go that far, since 5 could be a common denominator.This is how you do it:


1=(1)/(1) *(5)/(5)=(5)/(5) \\ \\(2)/(5)= (2)/(5)\\\\(6)/(10) =(6/2)/(10/2)=(3)/(5)

3. Take all the rewritten fractions and rewrite the operation.
(5)/(5) +(2)/(5) -(3)/(5)

4. Solve.


(5)/(5) +(2)/(5) -(3)/(5) =(5+2-3)/(5) =(4)/(5)

5. Express your result.


1+(2)/(5) -(6)/(10)=(4)/(5).
