Question

The students in the service club are mixing paint to make a mural. The table below shows the different parts of paint that the students mix together.
Two mixture of paint will be the same shade if the red and white paint are in the same ratio. how many shades of paint did the students make? Explain

Answer 1

There are really only two different shades of what I think is pink.

1/3 is equal to 2/6 which is equal to 3/9

1/2 is equal to 2/4 which is equal to 4/8

The bolded ones are the original mixtures given.

Start with 1/3 Multiply top and bottom by 2 and you get 2/6

When you multiply top and bottom of 1/3 by by 3 you get 3/9

Use the same idea for 1/2
