You can put this solution on YOUR website!
First solve in the parentheses, then move outwards.
2%2F3%2F3%2F4=2%2F%283%2A3%2A4%29=1%2F%283%2A3%2A2%29=1%2F18
%284%2F5%29%2A%285%2F6%29=2%2F3
1%2F2%2B%282%2F3%2F3%2F4%29-%284%2F5%2A5%2F6%29=1%2F2%2B1%2F18-2%2F3
For fractions, you need a common denominator, use 18.
1%2F2=%281%2F2%29%289%2F9%29=9%2F18
2%2F3=%282%2F3%29%286%2F6%29=12%2F18
1%2F2%2B%282%2F3%2F3%2F4%29-%284%2F5%2A5%2F6%29=1%2F2%2B1%2F18-2%2F3
1%2F2%2B%282%2F3%2F3%2F4%29-%284%2F5%2A5%2F6%29=9%2F18%2B1%2F18-12%2F18
1%2F2%2B%282%2F3%2F3%2F4%29-%284%2F5%2A5%2F6%29=%289%2B1-12%29%2F18
1%2F2%2B%282%2F3%2F3%2F4%29-%284%2F5%2A5%2F6%29=%28-2%29%2F18
1%2F2%2B%282%2F3%2F3%2F4%29-%284%2F5%2A5%2F6%29=-1%2F9
