Question

rosy waxes 2/3 of her car with 1/4 bottles of a car wax. at this rate, what fraction of the bottle of car wax will rosy use to wax her entire car?

Answer 1

The rate would be 2 and 2/3

Answer 2

(b/4)/(2c/3)=xb/c

(b/4)(3/(2c))=xb/c

3b/8c=xb/c

x=3/8

So Rosy will use 3/8 of a bottle to wax her entire car.
