Step-by-step explanation:
[tex](1\frac{1}{3} )(1\frac{1}{2} )(1\frac{1}{5} )\\(\frac{4}{3} )(\frac{3}{2} )(\frac{6}{5} )\\(\frac{2}{1} )(\frac{1}{1} )(\frac{6}{5} )\\\frac{12}{5}[/tex]
In the second step I made them all into simple fractions, just because that's easier.
In the third step I did a bit of cancelling to simplify everything as much as possible.
Answer:
[tex]\frac{12}{5}[/tex]
