The quotient of two fraction is the multiplication between the first and the inverse of the second:
So, in your case, you have
So, the question now is: which is larger, 7/10 or 3/5? To answer this question, transform the second fraction so that it will have denominator 10 as well:
So, now it is clear that

156 divided by 4 is 39 So each side is 39
Answer:
72
Step-by-step explanation:
you take 85 * 9
85 = # of seats
9 = # of buses
then you get 765
next, you take 765 - 693
765 = # of seats
693 = # people who bought tickets for a trip
finally you get 72
72 = # of empty seats
Since they're vertical angles, they're equal in degree measure
since they're equal, we can make the two expressions equal to each other
5a - 1 = 2a + 20
add 1 to both sides
5a = 2a + 21
subtract 2a from both sides
3a = 21
divide both sides by 3a
a = 7
now, plug the answer you found for a into one of the two expressions
5a - 1 becomes (5*7) - 1, which equals 34
to double check that they're equivalent (since they're vertical angles)
2a + 20 becomes (2*7) + 20, which equals 34
both angles are 34 degrees!
