What is the common denominator of 3/5, 7/8, and 5/6?

Hello from MrBillDoesMath!

240 is one common denominator.

(Not asked for by problem but  least common denominator is 120)

Discussion:

A common denominator (one of many) is given by multiplying the denominators: 5, 8, and 6. That is 5*8*6 = 240 is a common denominator.

If the least common denominator is desired, then that is 5 * 8 * 3 = 120

(we use 3 as 6 = 2*3 but 2 is already accounted for in the factorization of 8)

Thank you,

MrB

LCD (3 /5 , 3/ 4 ) = LCM(5, 4) = 2²×5 = 20

Step-by-step explanation:

The lowest common denominator or least common denominator (abbreviated LCD) is the least common multiple of the denominators of a set of fractions. It is the smallest positive integer that is a multiple of each denominator in the set.

First multiply 5 * 7 which equals 35. Then, it's going to be 35/5. So 35 is the common the denominator.
