When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?
It is easier to multiply or divide fractions than to add or
subtract fractions because in multiplication, you just have to
multiply the numerator by the numerator and the denominator by the
denominator. Same applies with division of fractions, except that
you have to reciprocate the fraction you're dividing with (divisor)
then proceed to multiplication.
Whereas, in addition and subtraction of fractions, you still
have to get their Least Common Denominator (LCD).
