Question

multiplying and dividing rational numbers word problems.....I have a test tomorrow so I need all the help I could get

Answer 1

Multiplication

`(3)/(4)*(8)/(3)`

you multiply the numbers that are in front

`\begin{gathered} (3*8)/(4*3) \\ \\ (24)/(12) \end{gathered}`

then simplify and the answer is 2

Division

`((3)/(4))/((8)/(3))`

you multiply the extremes and the solution is the numerator of the result

then multiply the internals and the solution is the denominator of the result

`\begin{gathered} (3*3)/(4*8) \\ \\ (9)/(32) \end{gathered}`

Other exercise about division

so the solution is

`(12)/(2)=6`
