Question

What is the algorithm for multiplying rational numbers

Answer 1

To multiply a rational number(fraction), you multiply across the numerators and denominators. For example:
`(A)/(B)`×
`(X)/(Y)`=
`(AX)/(BY)` or if
`(3)/(5)`×
`(3)/(6)`=
`(9)/(30)` which you need to reduce by 3 since it is a common multiple
`(9)/(30) = (3)/(10)`
