Question

I'd like 75% of my order to be 3 cupcakes and the rest cookies.
How many cookies do I get?

Answer 1

1 cookie

Explanation:

75% = 75/100

75 and 100 are both divisible by 25, therfore the simplified verision is 3/4

`(75)/(100) /(25)/(25) =(3)/(4)`

in order to get 100% we would need to:

3/4 + num of cookies = 4/4

re-arranged by subtracting 3/4 on bith sides:

num of cookie = 4/4 - 3/4

num of cookie = 1/4

meaning 1/4 of her orders is cookies
