Answer:
y = 2
Step-by-step explanation:
Given
= 
( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
Okay for this question, you make a simple equation: (1/3)x=(1/4)y to represent the ratio between the milk and water. Then to find how many cups of water are needed for each cup of milk, you plug in 3 for x (because 1/3 times 3 equals one cup) and solve for your y value. Your final equation for solving should look like: (1/3)(3)=(1/4)y
