The jelly junior high school color is made by mixing red oaint and yellow the ratio is 3 to 5 how monch red paint needed to be mix if u have 20 oz of yellow

3/5 = x/20

Cross multiply and solve for x.

12

To find out how much red paint is needed to make the Jelly Junior High School color, we need to calculate the ratio between red paint and yellow paint.

The given ratio is 3 to 5. This means that for every 3 parts of red paint, there are 5 parts of yellow paint.

We also know that we have 20 oz of yellow paint available. To find out how much red paint is needed, we need to set up a proportion using the ratio:

3 parts of red paint / 5 parts of yellow paint = x (unknown amount of red paint) / 20 oz of yellow paint

Cross-multiplying, we get:

(3/5) * 20 = x

Now, let's solve for x:

(3/5) * 20 = x
12 = x

Therefore, you will need 12 oz of red paint to mix with 20 oz of yellow paint to create the Jelly Junior High School color.

3/5=x/20

cross multiply and slove for x
