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.

Step-by-step explanation:

As per given, The ratio of blue paint to yellow paint is $\frac34: \frac{5}{6}$.

$=3\times6:5\times4\\\\=18:20\\\\ =9:10$

Total green paint = $4\frac34$ quarts

Quantity of yellow paint required = $\frac{10}{9+10}\times4\frac34$

$=\frac{10}{19}\times\frac{19}{4}\\=\frac{5}{2}\\=2.5\ quarts$

Hence, We need 2.5 quarts of yellow paint.
