Question

What is the solution to the proportion? Start Fraction 3 y minus 8 over 12 End fraction equals start fraction y over 5 End Fraction?

Answer 1

1.78

Explanation:

To solve for x we need to cross multiply it

We have = sign in between the fractions so we cross multiply it

9*x = 2* 8

9x = 16

Now we divide by 9 on both sides

so x= 1.7777777778

When we round to two decimal places then

x= 1.78

Answer 2

we have that

(3y-8)/12=(y/5)---------> 5*(3y-8)=12*(y)
15y-40=12y-------------> 15y-12y=40
3y=40--------------> y=40/3

y=(40/3)----------> 13.33

the answer is y=40/3 (13.33)
