Question

Mr. Frank purchased 5 1/4 pounds of rocks. He used 3/5 of a pound on one aquarium. He then split the rest of the rocks between his three remaining aquariums. How many rocks will be in one of the aquariums?

Answer 1

Answer:

1.55 pounds or 1 33/60 pounds

Step-by-step explanation:

5 1/4 = 5.25

3/5 = .6

remaining rock = 5.25 - .6 = 4.65

Divided into 3 aquariums i.e. 4.65/3 = 1.55 pounds

Alternative way:

Remaining rock = 5 1/4 - 3/5 = 93/20

Divided into 3 aquarium = 93/(20*3) = 1 33/60 pounds
