1 answer:
Answer:
140
Step-by-step explanation:
We have been given two fractions and
. We are asked to find the least common denominator of both fractions.
To find the least common denominator of both fractions, we will find least common multiple of 20 and 28.
Prime factorization of 20:
Prime factorization of 28:
Least common multiple of 20 and 28 would be: .
Therefore, the least common denominator of both fractions would be 140.
