if it takes 28 drops of green food coloring to turn a gallon of milk green. How many drops would it take to turn an 8 ounces cup of milk green?

7/4 or 1.75 drops

Step-by-step explanation:

In one gallon there are 128 ounces, if it takes 28 drops of coloring to turn 128 ounces of milk green then:

28/128

7/32

it takes 7/32 drops of food coloring to turn one ounce of milk green.

for 8 ounces, you multiply it by 8:

8*7/32

7/4≈1.75

∴ It would take 1.75 or 7/4 drops of coloring to turn 8 ounces of milk green.
