Question

The nestle house cookie recipe used 4.5 cups of flour, 3.5 cups of granulated sugar, and .75 cups of brown sugar what is the ratio of:
a. granulated to brown sugar?
b. flour to brown sugar?
c. flour to all sugar?

Answer 1

You can just substitute the names for the numers: (all sugar was 3.5+0.75=4.25)

a. granulated to brown sugar?
3.5:0.75
b. flour to brown sugar?
4.5:0.75
c. flour to all sugar?
4.5:4.25

but this looks ugly, so we can simplyfy it. Now, we can mupltiply all numbers by 100! (this will get rid of the .)


a. granulated to brown sugar?
350:75
b. flour to brown sugar?
450:75
c. flour to all sugar?
450:425


and they all are mupliples of 25, so let's divide all by 25!

a. granulated to brown sugar?
14:3
b. flour to brown sugar?
18:3
c. flour to all sugar?
18:17


now they all look good, but the second one can still be simplified:


a. granulated to brown sugar?
14:3
b. flour to brown sugar?
6:1
c. flour to all sugar?
18:17

that's the answer!
