Answer 1

−2/5+1/2=1/10

Explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(−2/5×2/2)+(1/2×5/5)=?

Complete the multiplication and the equation becomes

−4/10+5/10=?

The two fractions now have like denominators so you can add the numerators.

Then:

−4+5/10=1/10

This fraction cannot be reduced.

Therefore:

−25+12=110

Answer 2

1/10

Explanation:

-2/5 + 1/2

-4/10 + 5/10

-4 + 5/10

= 1/10

Hope this helps!
