%282%2F3%29X%2B5=10first thing is to subtract 5 from both sides of = sign
%282%2F3%29X=5 with a fraction before X you would want to multiply by its reciprical to both sides
cross%28%283%2F2%29%282%2F3%29%29X=5%283%2F2%29
highlight%28X=15%2F2%29


%2811%2F12+-+5%2F9%29%2F%282%2F3%29 find the Lowest Common Denominator for the 2 fractions in the numerator 9*4=36 and 12*3=36 so 36 is the LCD to change the fractions multiply by the common one to get 36 as the denominator
%28%28%2811%2F12%29%283%2F3%29%29-%28%285%2F9%29%284%2F4%29%29%29%2F%282%2F3%29multiply across numerator
%28%2833%2F36%29-%2820%2F36%29%29%2F%282%2F3%29subtract the numerator fractions
%2813%2F36%29%2F%282%2F3%29when dividing by a fracton it is the same as multiplying by the fractions reciprical
