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

$5d = 185 \iff d = \dfrac{185}{5} = 37$

So, the daughter weights 37 pounds.
