Question

A certain paint is to be mixed with 3 parts yellow to 2 parts blue.

What is the ratio of yellow paint to the total amount of mixed paint?

3 to 1
2 to 3
3 to 2
3 to 5

Answer 1

To find the ratio of yellow paint to the total amount of mixed paint, we start by determining the total amount of paint based on the given parts of yellow and blue.

We have:
- Yellow paint: 3 parts
- Blue paint: 2 parts

The total amount of mixed paint is:
\[
3 \text{ (yellow)} + 2 \text{ (blue)} = 5 \text{ parts}
\]

Now, to find the ratio of yellow paint to the total amount of mixed paint, we set up the ratio:
\[
\text{Ratio of yellow paint to total paint} = \frac{3 \text{ (yellow)}}{5 \text{ (total)}}
\]

This can be expressed as:
\[
\text{Ratio} = 3:5
\]

Therefore, the ratio of yellow paint to the total amount of mixed paint is **3 to 5**.

The correct answer is:
**3 to 5**.
