Final answer:
To solve y/12 = 5/7, cross multiply to get 7y = 60 and then divide by 7 to find y equals 8.57.
Step-by-step explanation:
When solving the equation y/12=5/7, you want to find the value of y.
Since the equation is a proportion, you can solve for y by cross-multiplying.
Multiply each side of the equation by 12 to get rid of the denominator next to y.
After cross-multiplying, you should end up with the equation 7y = 5 × 12.
Simplify that to get 7y = 60.
Now, to isolate y, divide both sides by 7 which gives you y = 60/7.
Therefore, y equals 8.57, which is the simplified form of 60 divided by 7.
