All you are basically doing is making ratios.
Basketball to football would be 5 to 11 or 5:11 or 5/11.
What you do is in the order you said it (basketball to football) you find that info and make it a ratio. A ratio must be simplified and can be written 3 ways, as shown above.
Hockey to lacrosse would be 6 to 10 and simplified would be 3 to 5.
Try doing 3 and 4 and 5 on your own to help you understand it more:) if you have any questions tell me.
Yes I can help you with the question you have displayed
B, x=12 because 140-80=60, 60/5=12
Reversing the clauses of an "if-then" statement only sometimes makes the new statement true, so it isn't true or false. For example, reversing the clauses of "if 1=x, then x=1" makes the new statement true, but reversing the clauses of "if x=2, then |x|=2" doesn't.
