A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers. To simplify a fraction: divide the top and bottom by the greatest number that will divide both numbers exactly (they must stay whole numbers).

Addition of two expressions with different denominators Change each of the fractions same as the LCD by multiplying the numerators as well as the denominator of each expression by any factors which make it equal to the LCD. Step 3. Add both of the numerators.

Add fractions the easy way You can use the easy way when the numerators and denominators are small (say, 15 or under). Here's the way to do it: Cross-multiply the two fractions and add the results together to get the numerator of the answer. Multiply the two denominators together to get the denominator of the answer.

Notice that adding (subtracting) fractions with the same denominator is very simple-we simply add (subtract) the numerators and divide by the same denominator. We should already know that we can write equivalent fractions that have different numerators and denominators.
