hi

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

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

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

Can you continue from where i stopped ?

thanks for answering, i understand the first bit, would it then be $\frac{3}{6}$ X $\frac{5}{6}$ ?

nope , its $3\times \frac{5}{6}$ because

$\frac{3}{\frac{5}{6}}=\frac{\frac{3}{1}}{ \frac{6}{5} }$

$<br /> =\frac{3}{1}\times \frac{5}{6}<br />$

i understandnow, so for the answer would i do

$\frac{3}{1}$ X $\frac{5}{6}$ = $\frac{15}{6}$ , then i can simplify it?
