Question

in order to make green paint, a 2:3 ratio of blue paint to yellow paint is used. If there are 30 ounces of green paint how many ounces of blue paint was used?

Answer 1

Answer:

12 ounces

Step-by-step explanation:

• Totally there are 5 parts (2+3)

• One part = 30/5 = 6
• Blue = 2 parts = 6*12 = 12 ounces

Answer 2

Answer:

let the proportion of blue and yellow colours be 2x and 3x

so a.t.q

2x+3x=30ounce

5x=30 ounce

x=30/5ounce

x=6ounce

so blue paint used=2x=2*6=12ounce

yellow paint used=3x=3*6=18ouncd
