Question

a chef used 1/10 of a bag of potatoes to make 1/6 of a gallon of stew. if he wanted to make a full gallon of stew how many bags of potatoes would he need?

Answer 1

(1/10) / (1/6) = x / 1.....1/10 bag to 1/6 gall = x bags to 1 gall
cross multiply
(1/6)(x) = (1/10)(1)
1/6x = 1/10
x = (1/10) / (1/6)
x = 1/10 * 6/1
x = 6/10 which reduces to 3/5 bags <==
