Question

Water makes about 3/4 of a person’s weight. If a student weighs 100 lbs., how much of his weigh is water?

Answer 1

75 pounds

To solve this problem, find 3/4 of 100.

To multiply fractions, multiply the numerators by each other and the denominators by each other.

3/4 * 100/1

Evaluating 3*100 and 4*1, the fraction becomes 300/4.

Now, divide 300 by 4 to get the final answer. 300/4 = 75. Therefore, 75 pounds of the students weight is water.
