≠
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.

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
