Question

There are 53 milligrams of Vitamin C in 100 grams of orange. How many grams of orange do you need to eat to get 550 milligrams of Vitamin C? Round your answer to the nearest Gram

Answer 1

Set up a proportion. 

53 = 550
100  x          Cross multiply.

53x = 55000     Divide both sides by 53.

x = 1037.73585 grams.

This would round up to 1038 grams of orange.
