When the numerator is less than the denominator then it is a common fraction but if the numerator is greater than the denominator then it is an improper fraction.

If the sum of the numerators is greater than the denominator the sum is greater than 1. If the sum of the numerators is equal to the denominator the sum is equal to 1. If the sum of the numerators is less than the denominator the sum is less 1.

That is why it is called an improper fraction because a proper or a common fraction always has its numerator less than its denominator.

The least common denominator is the least common multiple of the denominators of the fractions.

A common denominator is needed when adding or subtracting fractions of different denominators.

if you are adding two fractions that are both greater than 1/2, what must be true about the sum?

Assuming the fractions are "normalized" (the fractional part is less than 1): First compare the integer part. If the integer part is the same, you need to compare the fractions. If the denominator of the fractions is different, you have to convert to a common denominator. The simplest way to find a common denominator is to multiply both denominators (i.e., you don't need the LEAST common denominator - any common denominator will do).

By converting to a common denominator (convert 1/2 to twelfths), and comparing. Because 5 is less than half of 12.
