hi

first ly , write $\displaystyle 1\frac{1}{5}$ as an improper fraction ie $\displaystyle \frac{6}{5}$

Then $\displaystyle \frac{3}{\frac{6}{5}}=3\times \frac{5}{6}$ .. do you see why ?

Because when you divide a fraction , it means multiplying its reciprocal .

Can you continue from where i stopped ? - Sep 18th 2009, 07:36 AMandyboy179

i understandnow, so for the answer would i do

$\displaystyle \frac{3}{1}$ X $\displaystyle \frac{5}{6}$ = $\displaystyle \frac{15}{6}$ , then i can simplify it? - Sep 18th 2009, 07:55 AMmathaddict
