Fractions – Adding Fractions
When adding fractions the first thing you must check for is a common denominator. If the denominators are different, you must make equivalent fractions, then add numerators and keep your denominator the same.

Fractions – Adding Fractions
When adding fractions the first thing you must check for is a common denominator. If the denominators are different, you must make equivalent fractions, then add numerators and keep your denominator the same. EXAMPLE # 1 : Common denominator When denominators are the same, add your numerators, keep the same denominator…
