The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 2) = 8. The fraction result cannot be further simplified by cancelling.
In words - three eighths plus one half = seven eighths.
Answer:7/8
Step-by-step explanation:The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(3/8, 1/2) = 8
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.
(3/8×1/1)+(1/2×4/4)=?
Complete the multiplication and the equation becomes
3/8+4/8=?
The two fractions now have like denominators so you can add the numerators.
Then:
3/8+4/8=7/8
This fraction cannot be reduced.
