Name a pair of fractions that use the least common denominator and are equvivalent to 9/10 and 5/6

Answers

When we have two fractions, it's best to find the least common denominator.

This means that we need two fraction that are EQUAL to the other two, but have different denominators (must be the smallest but common).

Alright, let's multiply


9/10 * 3/3  = 27/30
5/6 * 5/5 = 25/30

Now we have our two fractions:

27/30 and 25/30
