Question

The Jelly Junior High school color is made by mixing red paint with yellow paint. The ratio of red to yellow is 3 to 5. How much red paint should be mixed with 20oz of yellow?

Answer 1

The total ratio of red to yellow is 3 + 5 = 8.

To find the amount of red paint needed, multiply the ratio by the amount of yellow paint: 20 oz yellow * (3/5) = <<20*(3/5)=12>>12 oz red. Answer: \boxed{12}.

Answer 2

To determine the amount of red paint needed, let's first calculate the ratio of red to yellow in terms of ounces.

The total ratio is given as 3:5, which means there are 3 parts of red for every 5 parts of yellow. Since the question specifies the amount of yellow paint to be 20oz, we can use this information to determine the amount of red paint needed.

Let's assume the amount of red paint needed is "x" ounces:

Red to yellow ratio: 3/5 = x/20

To solve for x, we can cross-multiply:
(3/5) * 20 = x
12 = x

Therefore, 12 ounces of red paint should be mixed with 20 ounces of yellow paint.

Answer 3

To determine how much red paint should be mixed with 20oz of yellow, we first need to find the ratio of red to yellow. In this case, the ratio is given as 3 to 5, which means for every 3 parts of red paint, there are 5 parts of yellow paint.

Next, we need to determine how much red paint corresponds to 20oz of yellow. One way to do this is by setting up a proportion. Since the ratio of red to yellow is 3 to 5, we can write the proportion as:

red/amount of red = yellow/amount of yellow

We know that the amount of yellow paint is 20oz, so we can substitute those values into the equation:

red/amount of red = yellow/20oz

Now, we can cross-multiply and solve for the amount of red paint:

red * 20oz = yellow * amount of red

To find the value of red, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 5:

(red * 20oz) / 5 = (yellow * amount of red) / 5

Simplifying, we get:

4 * red = yellow * amount of red

Since the amount of yellow paint is 20oz, we substitute that value into the equation:

4 * red = 20oz * amount of red

Now, we can cancel out the factor of "amount of red" on both sides:

4 = 20oz

Finally, we can solve for the amount of red paint by dividing both sides of the equation by 4:

red = 20oz/4

Simplifying, we find:

red = 5oz

Therefore, to mix with 20oz of yellow paint, you would need 5oz of red paint.
