2. Avery is painting more tables. It takes 1/4 gallon of paitn to cover a table. IF she has a 5/6 gallon of paint, how many tables can she cover?

A) Write a division number sentence that relates to your model:

B) Write a multiplication number sentence to check your answer:

C) Show how many tables Avery paints:

You can do this with a proportion. It takes 5/6 of a gallon to paint 1 wall and you want to know how much of a wall can you paint with 1/2 gallon. So set up the proportion:

5/6 / 1 = 1/2 / x

cross multiplying gets you 5/6x = 1/2

multiply by the reciprocal of 5/6 to isolate x - which is 6/5. 1/2 times 6/5 = 3/5
