An artist mixes 2/5 ounce of blue paint with 1/15 ounce of green paint. Using the same ratio, how many ounces of green paint should she mix with 3 ounces of blue paint?

Respuesta :

2/5 is equivalent to 6/15
3 ounces is equal to 45/15

she mixes 1/15 green for every 6/15 of blue or 5/15 less than blue so

she should mix 40/15 ounces or 2 10/15 or 2 2/3
