Multiply each numerator by the opposite denominator, otherwise known as cross multiply. Then compare these two products and determine which one is larger. The fraction that contributed the numerator (top number) to the larger product is the larger fraction.
For example:
Which is larger, 2/5 or 3/4?
Multiply 2 X 4 = 8
Multiply 3 X 5 = 15
Determine that 15 is larger than 8.
Determine that the fraction 3/4 contributed the numerator (top number) to the larger product, 15.
So 3/4 is larger than 2/5.

No, because there is an infinite number of possibilities smaller from the larger gives
The name of a fraction with a larger number on top is called an improper fraction.
