If 5 apples cost $3, how much would 8 apples cost?

Answer 1

Hi Chloe,

one way to solve the question is with proportions. We'll use apples as numerator and cost as denominator:

5 8

– = –

3 x

Cross-multiply (a.k.a multiply diagonally) and you get: 5x = 24

Divide both sides by 5 and you get: x = 4.8

Answer: If 5 apples cost $3, 8 apples would cost $4.80
