Byron wants to use the distributive property to rewrite the addition problem shown so that the numbers left in the parentheses have no common factor except 1.

(48 + 36)

Which is an equivalent expression that has numbers in the parentheses whose only common factor is 1?

By applying the distributive property, Byron can rewrite the addition problem as:

48 + 36 = (4*12) + (6*6)

This expression has numbers in the parentheses (12 and 6) whose only common factor is 1.
