No. Look at the examples below for an idea. All you so is multiply the numerators and the denominators. Although most schools require you to simplify, some you dont have to. Remember that cross-simplifying can help out! Good luck!

How do you sum two fractions?
Make the demoninators (bottom numbers) the same by multiplying the top and bottom of one (or both) fractions, then add them as you would with integers.
Why does the method of dividing fractions work?
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
Why do you have to switch the numerator and denominator when dividing fractions?
This is because dividing by a number is the same as multiplying by its reciprocal.
How is multiplying fractions different from adding fractions?
When multiplying fractions, the numerators (top numbers) are multiplied together and put as the numerator over the denominators (bottom numbers) multiplied together.When adding fractions, they must both have the same denominator - the fractions are made into equivalent fractions with a common denominator; then the numerators are added together and put over the same common denominator.In both cases of multiplication and addition, the resulting fractions are reduced to simplest form.
How do you use rectangular models for multiplying fractions?
Draw as many rectangles as the whole number you are multiplying by. Then, draw the fraction you are multiplying by in all of the rectangles. Shade in the top number in the fraction [numerator] in your rectangles. Count all the shaded in parts of all your rectangles. Leave the bottom number of your fraction [denominator] the same and put the number you got when you added the shaded parts of the rectangles on top as your denominator of the fraction. That is your answer!
