Answer:


\sf 1 (7)/(30)

Explanation:

2/5 + 5/6 =?

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

LCD(2/5, 5/6) = 30

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 × 6/6)+( 5/6 × 5/5)=?

Complete the multiplication and the equation becomes

12/30+25/30=?

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

Then:

12+25/30 = 37/30

This fraction cannot be reduced.

The fraction

37/30

is the same as

37÷30

Convert to a mixed number using

long division for 37 ÷ 30 = 1R7, so

37/30 = 1 7/30

Therefore:

2/5 + 5/6 =
1 (7)/(30)
