1. Cross multiply

12y = 5(15)

12y = 75

12y divided by 12 = 1y

75 divided by 12 = 6.25

y = 6.25

5 over 12 = 6.25 over 15

Answer:


\boxed{\sf{{y=(25)/(4)=6.25}}}

Explanation:

Solution: Multiplication property of equation solves this problem.


For the correct answer, you need to isolate Y from one side of the equation.


\sf{(5)/(12)=(y)/(15) }

You can also switch sides.

y/15=5/12

Multiply by 15 from both sides.


\sf{(15y)/(15)=(5*15)/(12)}

Solve.

5*15=75

75/12

Divide by 3.

75/5=25

12/3=4

Rewrite as a fraction.


\sf{y=(25)/(4) }

Dividing is another option.

25/4=6.25


\boxed{\sf{y=(25)/(4)=6.25 }}

Therefore, the final answer is y=25/4=6.25.

I hope this helps you! Let me know if my answer is wrong or not.
