QUESTION 3

•

Step 1 ) Multiply both sides by y.

$\displaystyle(3)/(y) = (5)/(2)$

↓

$\displaystyle\ 3 = (5)/(2) y$

↓

$\displaystyle\ 3 = (5y)/(2)$

Step 2 ) Multiply both sides by 2 and simplify.

6 = 5y

Step 3 ) Divide both sides by y.

$\displaystyle(6)/(5) = (5y)/(5)$

$\displaystyle(6)/(5) = y$

Step 4 ) Switch equation sides.

$\displaystyle(6)/(5) = y$

$\displaystyle\ y = (6)/(5)$

The proportion can be simplified no farther, so the final answer is...

$\displaystyle\ y = (6)/(5)$

QUESTION 4

•

Step 1 ) Multiply both sides by 5.

$\displaystyle(7)/(2) = (k)/(5)$

$\displaystyle(35)/(2) = k$

Step 2 ) Switch equation sides.

$\displaystyle(35)/(2) = k$

$\displaystyle\ k = (35)/(2)$

The proportion can be simplified no farther, so the final answer is...

$\displaystyle\ k = (35)/(2)$
