Answer:

2/5

Step-by-step explanation:

4 = 10q

Since we are trying to isolate the variable q, we need to divide by 10 on both sides (law of equivalent exchange... er... equivalency in math...).

4/10 = q

We now know that q is equal to 4/10, however, we can simplify this fraction down.

4/10 = 2/5

2/5 = q
