(-19)+9=-10, so there is 10 less people on the bus
Letter, it has just been placed differently. But it is the same answer.
(a/b) / (c/d) = (a/b)*(d/c) that is the rule so:
(3/4)/(3/16) is equal to:
(3/4)*(16/3) which is equal to
16/4

Subtract the thickness of the known piece from the total thickness.
Because they have different denominators rewrite them to have the same.
9/32 x 2 = 18/64
Now you have 33/64 - 18/64 = 15/64
The other piece is 15/64 inch thick.
I believe it is.... (2,2)or(4,4)
