Question

The two tables give the number of pints of red and blue paint that are used to make different amounts of two shades of purple paint.
Purple #1 is made by mixing red and blue in a ratio of 1 : 2.
Purple #2 is made by mixing red and blue in a ratio of 1 : 3.

Use the drop-down menus to complete each sentence below.

Answer 1

The combine ratios will be a1:a2:a3 = 1:2:3  as the a1 is equal to a2 and the 2:4 shows the mixing 2 red with 4 blue paint.

What is the ratio?

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign : between the numbers.

We have:

Purple 1 is made by mixing red(a1) and blue(a2) in a ratio of 1 : 2.

Purple 2 is made by mixing red(a3) and blue(a4) in a ratio of 1 : 3.

Here the options are not given, but we can combine the above ratios like:

a1:a2:a3 = 1:2:3  (a1 = a3)

If we multiply with any number (let's say 2) in the ratio 1 : 2 and 1 : 3

We get:

2:4  (mixing 2 red with 4 blue paint) and

2:6  (mixing 2 red with 6 blue paint)

Thus, the combine ratios will be a1:a2:a3 = 1:2:3  as the a1 is equal to a2 and the 2:4 shows the mixing 2 red with 4 blue paint.
