29. Trenton gave a total of 3

packs of baseball cards to his

friends. He gave each friend 1/3

of a pack. How many friends

does Trenton have?

Trenton has 9 friends

Step-by-step explanation:

Lets label the amount of friends Trenton has as f

1) Set up an equation using the variable we just made:

f (1/3) = 3

2) Multiply both sides of the equation by the reciprocal of 1/3 (3/1):

f=9

9 Multiplied by 1/3 equals 3, which means we were correct!
