=

≠

Solve each problem.

3.

2/3 = 1.2/x

x = 18

x = 1.8

x = 0.2

x = 10

4.

4/5 equals 8/x plus 2

x = 4

x = 9.5

x = 2

x = 8

Create a proportion and solve.

5.

A recipe uses 3 cups of flour to make 48 cookies. How much flour is needed to make 72 cookies? (1 point)

3/48 = 72/x, x = 1,152 cups

3/48 = x/72, x = 4.5 cups

3/48 = x/72, x = 2 cups

x/48 = 3/72, x = 2 cups

Here are my answers. Are they correct? Thanks!

1. ≠

2. =

3. 1.8

4. x = 8

5. 3/48 = x/72, x = 4.5 cups
