How many white cups of paint if there is 4 cups of red?

And how many red cups would there if if there was 5 cups of white paint?

Answer 1

1) $7/3$ cups of white paint used for 1 red cup of paint
2) 

Answer 2

Answer :

The number of cups of white paint used is, $\frac{4}{3}$

The number of cups of white paint used is, $\frac{16}{3}$

The number of cups of red paint used is, $\frac{15}{4}$

Step-by-step explanation :

As we are given that a pink paint mixture uses 4 of white paint for every 3 cups of red paint.

Now we have to determine the number of cups of white paint used for 1 red cup of paint.

As, 3 cups of red paint uses the number of cups of white paint = 4

So, 1 cup of red paint uses the number of cups of white paint = $\frac{1}{3}\times 4=\frac{4}{3}$

Thus, the number of cups of white paint used is, $\frac{4}{3}$

Now we have to determine the number of cups of white paint used for 4 red cup of paint.

As, 3 cups of red paint uses the number of cups of white paint = 4

So, 4 cups of red paint uses the number of cups of white paint = $\frac{4}{3}\times 4=\frac{16}{3}$

Thus, the number of cups of white paint used is, $\frac{16}{3}$

Now we have to determine the number of cups of red paint used for 5 red cup of paint.

As, 4 cups of white paint uses the number of cups of red paint = 3

So, 5 cups of white paint uses the number of cups of red paint = $\frac{5}{4}\times 3=\frac{15}{4}$

Thus, the number of cups of red paint used is, $\frac{15}{4}$
