3+9%2F10 * 4+8%2F12
convert mix number into improper fraction
recall that 3+9%2F10 is 3%2B9%2F10=30%2F10%2B9%2F10=39%2F10
and 4+8%2F12 is 4%2B8%2F12=48%2F12%2B8%2F12=56%2F12

%2839%2F10%29%2856%2F12%29... simplify
%2839%2F10%29%28cross%2856%2914%2Fcross%2812%293%29
%28cross%2839%2913%2Across%2814%297%29%2F%28cross%2810%295%2Across%283%29%29
%2813%2A7%29%2F5
91%2F5
as a mixed number
91%2F5=90%2F5%2B1%2F5=18%2B1%2F5
181%2F5
