Use cross products to see if each pair of ratios forms a proportion. Replace each box with = or ≠.

1. 7/5 ? 15/10

=
≠ <---


2. 6/8 ? 15/20

= <---




Solve each problem.

3. 2/3 = 12/x

x = 18 <---
x = 12
x = 36
x = 8


4. 6/11 = 84/x

x = 40
x = 120
x = 254
x = 154 <---


5. 22miles/55hours = 12/miles/Hhours

a recipe uses 3 cups of to make 48 cookies .how much flour is needed to make 72 cookies
Answered by Bot
To answer this question, we can set up a proportion:

3 cups of flour / 48 cookies = x cups of flour / 72 cookies

We can cross-multiply to solve for x:

3 * 72 = 48 * x

216 = 48x

Divide both sides by 48 to solve for x:

x = 216 / 48

x = 4.5

Therefore, 4.5 cups of flour is needed to make 72 cookies.
