A tiger ate food that weighed 15% of its body weight. If it ate 75lb., how much does the tiger weigh?

75lbs of food = 15% tiger's food weight

? lbs tiger = 100% tiger's body weight

So you want to take the amount of food (75lbs), divide it by the amount of the tiger's food weight (15%) and then multiply it by it's total body weight (100%)

So 75 / 15 = 5

and 5 x 100 = 500

so the tiger = 500lbs

11.25 lbs, if I calculated this correctly.
