Question

How are equivalent fractions used in writing a sum of two like fractions in simplest form?

Answer 1

Equivalent Fractions can be cut down when the upper and lower value have a same factor in them. If the upper and lower value has a same factor, then we can withdraw the factors out.

For example, in the fraction 69  69 , 3 is the common factor of both 6 and 9.

=

In this, we can simplify the fractions by canceling the 3 from both the upper and lower of the fraction. Canceling means dividing both the upper and lower by the same number.

= = is equivalent to =

Hope this helps! :D

Answer 2

A proportion. These are two equal fractions, where one is missing (x) and you cross multiply to find what x is.
