Question

A research scientist estimates that the human body contains 88 punds of water for every 100 pounds of body weight. at this rate, estimate the number of pounds of water in a college student who weighs 175 pounds__lb

Answer 1

This is a problem of creating fractions that are similar. If you say 88/100 = x/175 then you can cross multiply and solve for x to get your answer

Answer 2

For every 100 lbs of body weight there are 88 lbs of water

so for every 75 lbs of body weight there must be 66lbs water.

Now we have 100 and 75 lbs, which u can add to get 175lbs

since 100lbs body is 88 lbs water and 75lbs body is 66 lbs water, so add 

88lbs+66lbs=154 lbs of water
