85 / 15 = 5 2/3
30 x 5 = 150
2/3 x 30 = 20
The answer is 170 seconds, or 2 minutes and 50 seconds
What you must do for this case is to rewrite the expression in a simplified way.
We have then:
3/a-9b
We take common factor 3:
(3)*(1/a-3b)
Answer:
The simplified form of the expression is:
(3)*(1/a-3b)
Answer:
c
