To add like fractions you just add the numerator and keep the denominator the same. To add related fractions you find an equivelant fraction for one fraction that has the same denominator as the other fraction you're adding and then they're like fractions so then you add the numerator and not the denominator

Ordering fractions. If all the denominators are the same then you look at the numerators and the smallest numerator is the smallest fraction and the biggest numerator is the biggest fraction. Finding equivalent fractions. You have to use the same operation and use the same numbers on the denominator and the numerator. For example if you have five tenths you can find an equivalent fraction by multiplying the denominator and the numerator by three. Then you would have fifteen thirtieths and that is an equivalent fraction. Simplifying fractions. You find the equivalent fraction that has the smallest numbers by dividing the numerator and the denominator by the same number.
