Question

Lisa and her daughter weigh 185 pounds all together. The ratio of lisa’s weight to her daughter weight is 4:1 . How much does lisa weight ? How much does her daughter weigh

Answer 1

Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.

In fact, if the daughter weights
`d` pound, the mother weights
`4d` pounds, and the total weight is
`d+4d = 5d`.

We know that this total is 185 pounds, so we have

`5d = 185 \iff d = (185)/(5) = 37`

So, the daughter weights 37 pounds.
