The jelly junior high school color is made by mixing red paint to yellow is 3 to 5, How much red paint should be mixed with 20 oz of yellow?
3/5=x/20
5x=20x3
5x=60
x=60/5
x=12
12 ounces:)
Cross multiply and solve for x.
3/5 = x/20
12 oz.
Don't know if makes to much sense but
the 5 to 3 part which 5-3 is 2 and 3*2 is 6 that's how i got my answer
5 to 3
5-3=2
3*2=6
