Answer:
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 =
