Question

A train car can hold 22 passengers. If there are 140 passengers, how many train cars will be needed to carry all of them?

Answer 1

7 train carriages are needed.

Answer 2

The answer is 7 train cars. Divide 140 into 22 and you get 6.3636. But dont get tricked, the answer is not 6! what are you going to do with the other passengers? you'd add another train car for them, equaling 7 train cars needed.
