Answer 2

Sally had 20 bars of chocolate and shared them equally between her friends. If each of her friends received 2 1/2 bars of chocolate, how many friends did Sally have?

let x = number of friends

Solve: 20 ÷ x = 2 1/2

Multiply both sides by x:

⇒ 20 = 2 1/2 x

Multiply both sides by 2:

⇒ 40 = 5x

Divide both sides by 5:

⇒ 8 = x

Therefore, Sally had 8 friends.
