Question

one gram of fat contains 180% of the calories of a gram of a carbohydrate. How many more calories are there in 8 grams of fat than there are in 8 grams of carbohydrate?

Answer 1

14.4

Explanation:

180% is the same as the number 1.80. Each gram of fat contains 1.80 times as many calories as a gram of carbohydrate. 8 grams of fat will contain 8 times as much: 1.80 · 8 = 14.4.

Answer 2

There will be 6.4 more calories of fat than calories of carbohydrate

Explanation:

1 gram of fat = 180% of calories of 1 gram of carbohydrate

Which simple implies that

1 gram of fat = 180 /100 of calories of 1 gram of carbohydrate

1 gram of fat = 1.8 calories while 1 gram of carbohydrate = 1 calories

Therefore

8 gram of fat = (1.8 x 8) calories while 8 gram of carbohydrate = 8 calories

8 gram of fat = 14.4 of calories while 8 gram of carbohydrate = 8 calories

Therefore there will be (14.4 - 8) more calories of fat than calories of carbohydrate

= 6.4 more calories of fat.
