Answer 1

Do you know how to divide fractions? The trick is knowing that a man rides a horse and the man is on the top of the horse. The man is in the numerator and the horse is in the denominator. For example lets look at 120/10.

Write out the division problem using a house. The man goes in the house and the horse stays outside the house. So the problem is 120 divided by 10, not 10 divided by 120. The answer is 12!
