What does it mean to multiply and divide fractions?
multiply and divide fractions!-.-
How is dividing fractions different from multiplying fractions?
(3/4) x (5/9) = (3x5)/(4x9) = 15/36, that is when you multiply fractions, you multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result (3/4) / (5/9) = (3/4) x (9/5) = 27/20, that is when you divide fractions, you first invert the fraction by which you are dividing and then multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result
When you multiply fractions do you multiply the bottom numbers too?
Yes.
How do you multiply fractions with different denominators?
To multiply fractions, multiply the numerators together and the denominators together. For fractions a/b and c/d, the answer will be (a x c) / (b x d). Then simplify if possible. Numerical example : 2/5 x 3/8 = (2 x 3)/ (5 x 8) = 6/40 which equals 3/20
