Question

Using the fractions 2/3 and 3/4 describe how to give two fractions common denominators

Answer 1

When the denominators can't divide into each other, you multiply each fraction by the other fractions' denominator to get a common denominator

It looks like this:

`(2)/(3)*( (4)/(4) )= (8)/(12)`


`(3)/(4)*( (3)/(3))= (9)/(12)`
now each denominator is 12

Answer 2

One way is to find the prime factorization for the denominators which are 3 and 4. The prime factorization of 3 would be 1 x 3 and 4 would be 2 x 2. Since we only use prime numbers to find the prime factorization we would have 2 x 2 x 3 = 12 which give us the the least common denominator for 2/3 and 3/4. Final answer is 12.
