What is a fraction pair that is equivalent to 2/15 and 4/9, and in which both fractions have a

Vesnalui [34]

Answer:

6/45 and 20/45

Step-by-step explanation:

The least common denominator is the least common multiple (LCM) of 9 and 15.

The factors of those numbers are ...

9 = 3·3

15 = 3·5

The LCM is the product of the unique factors to their highest powers:

3·3·5 = 45

To make 2/15 have a denominator of 45, we need to multiply by 3/3:

2/15·3/3 = 6/45

To make 4/9 have a denominator of 45, we need to multiply by 5/5:

4/9·5/5 = 20/45

The desired fraction pair is 6/45 and 20/45.
