Why do you multiply and divide functions?
To multiply fractions you take the first fractions top, or the numerator, times the second fractions top. This is the top to the answer. Then you take the first fractions bottom, or denominator, times the second fractions bottom. This is the answers bottom. 2/3*7/5=14/5 To divide fractions, you take the second fraction and flip it over. Then you continue the same way as multiplying fractions, taking the first fraction times the flipped over second fraction. (2/3)/(7/5)=2/3*5/7=10/21
