So, it would take 14.25 hours for 19 car's tires to be changed.

Q · 7/9 = 4<br> What is q?
FrozenT [24]

Answer:

q = 36/7  or 5 1/7

Step-by-step explanation:

q · 7/9 = 4

Multiply each side by 9/7

q · 7/9 *9/7 = 4*9/7

q = 36/7

If we want it as a mixed number instead of an improper fraction

7 goes into 36 5 times with 1 left over

q = 5 1/7
