Question

`(3)/(5) times (7)/(12) divided by 2(7)/(10)` helpppppppppppppp i need this for 2morrow

Answer 1

let's first convert the mixed fraction to improper, and then proceed.

`\bf \stackrel{mixed}{2(7)/(10)}\implies \cfrac{2\cdot 10+7}{10}\implies \stackrel{improper}{\cfrac{27}{10}} \\\\[-0.35em] ~\dotfill`

`\bf \cfrac{3}{5}\cdot \cfrac{7}{12}/ \cfrac{27}{10}\implies \cfrac{3}{5}\cdot \cfrac{7}{12}\cdot \stackrel{\stackrel{notice}{\downarrow }}{\cfrac{10}{27}}\implies \cfrac{3}{27}\cdot \cfrac{7}{12}\cdot \cfrac{10}{5}\implies \cfrac{1}{9}\cdot \cfrac{7}{12}\cdot \cfrac{2}{1} \\\\\\ \cfrac{1}{9}\cdot \cfrac{7}{1}\cdot \cfrac{2}{12}\implies \cfrac{1}{9}\cdot \cfrac{7}{1}\cdot \cfrac{1}{6}\implies \cfrac{7}{54}`
