#21/55#

Explanation:

#3/11 div 5/7 = (3/11) / (5/7)#

Flip #5/7# and change the symbol from #div# to #xx#

#3/11 xx 7/5#

Multiply straight across, which gets you #21/55#.

#21/55#

Explanation:

When dividing fractions, you always flip the second fraction (numerator becomes denominator, denominator becomes numerator) and you multiply the two fractions.

#3/7*7/5#

So now you multiply the numerators by each other and the denominators by each other:

#(3*7)/(11*5)#

#21/55#

Hope this helps!
