Final answer:
To find the value of y in the proportion 2/3 = x/6 = 9/y, you can find the value of x using the first equality, 2/3 = x/6, then substitute the value of x into the second equality, x/6 = 9/y.
Step-by-step explanation:
To find the value of y in the proportion 2/3 = x/6 = 9/y, you can start by finding the value of x using the first equality, 2/3 = x/6. To do this, cross multiply:
2 * 6 = 3 * x
12 = 3x
x = 4
Next, substitute the value of x into the second equality, x/6 = 9/y, and cross multiply again:
4 * y = 6 * 9
4y = 54
y = 54/4 = 13.5
Therefore, the value of y in the proportion is 13.5. To find the value of y, you must divide 54 by 4.
Complete question is:
2/3 = x/6 = 9/y To find the value of y in this proportion, you must divide 54 by:
A.3
B.2
C.4
D. 6
