We know two things: The first is that Liam has 9/10 gallon of paint and the second is that each birdhouse requires 1/20 gallon of paint.
In order to calculate how many birdhouse Lian can paint with 9/10 gallon of paint we should divide 9/10 with 1/20:
(9/10) / (1/20)= 9*20/10=180/10=18
So, Liam can paint 18 birdhouses.

all together you can write

Ughh just ignore the "A" symbol .-.
