let's ? be x
%281%2F12%29%3A%281%2F8%29=+2%3Ax
%281%2F12%29x=+2%281%2F8%29
x%2F12=+cross%282%291%281%2Fcross%288%294%29
x%2F12=+1%2F4
x=+%281%2F4%2912
x=+12%2F4
x=+3
check:
%281%2F12%29%3A%281%2F8%29=+2%3A3
%281%2F12%29%2F%281%2F8%29=+2%2F3
8%2F12=+2%2F3....simplify 8%2F12, divide both 8 and 12 by 4
cross%288%292%2Fcross%2812%293=+2%2F3
2%2F3=+2%2F3 which is true
