Question

Margo won 24 out of her last 36 tennis matches. At this rate, predict how many matches she would win out of her next 27 matches? Show yoour work.

Answer 1

18...

24 - 36
??? - 27

24*27 = 648

648/36 = 18

Answer 2

we know that

Margo won
`24` out of her last
`36` tennis matches

so

by proportion

Find the number of matches she would win out of her next
`27` matches

`(24)/(36)(wins)/(matches)=(x)/(27)(wins)/(matches) \\ \\x*36=27*24\\ \\x=(27*24)/36\\ \\x=18\ wins`

therefore

the answer is

`18\ wins`
