Question

A mixture of paint calls for 1/3of a cup of red paint and 2/3 cups of yellow paint. How many cups of red paint would be needed for every 1 cup of yellow paint

Answer 1

1/2 a cup of red paint

Explanation:

To solve this, arrange the equations as follows;

If 2/3 of yellow paint requires = 1/3 cup of red paint,

then 1 cup of yellow paint would require = ?

=
`=((1 * 1/3))/(2/3) \\ \\ =(1)/(3) *(3)/(2)`

The 3s cancel each other and you remain with
`(1)/(2)`

Therefore 1 cup of yellow paint would need 1/2 a cup of red paint.
