Question

You mix 3/4 quart of blue paint for every 5/6 quart of yellow paint to make 4 3/4 quarts of green paint. How much blue paint and how much yellow paint do you use?

Answer 1

Answer: We need 2.5 quarts of yellow paint.

Explanation:

As per given, The ratio of blue paint to yellow paint is
`\frac34: (5)/(6)`.

`=3*6:5*4\\\\=18:20\\\\ =9:10`

Total green paint =
`4\frac34` quarts

Quantity of yellow paint required =
`(10)/(9+10)*4\frac34`

`=(10)/(19)*(19)/(4)\\=(5)/(2)\\=2.5\ $$ quarts$$`

Hence, We need 2.5 quarts of yellow paint.
