The lowest common denominator is 9/90 and 14/90, multiplying 1/10 by 9/9 and 7/45 by 2/2. I am assuming you know how to solve for LCD? If you don't I can explain in comments.
Answer:
Oil changes = 5
Vincent = 10 oil changes
Warren = 10 oil changes
Step-by-step explanation:
Vincent = 5 + h
Warren = 2h
Where,
h = number of oil changes
How long will that take?
Vincent = Warren
5 + h = 2h
5 = 2h - h
5 = h
h = 5
Number of oil changes = 5
How many oil changes will Vincent and Warren each have done?
Vincent = 5 + h
= 5 + 5
= 10 oil changes
Warren = 2h
= 2(5)
= 10 oil changes
