Question 775422
let the number be x, then
x+x/2+x/3=22 solve for x, common denominator would be 6, so
{{{6x/6+3x/6+2x/6=22}}} now that all the x terms have common denominator we can combine them...add the tops, leave the bottom
{{{(6x+3x+2x)/6=22}}} 
{{{11x/6=22}}} now multiply each side by the reverse of what's in front of x, so by 6/11, this will give you x by itself
{{{x=22*(6/11)}}} you can reduce top and bottom by 11 (ie 22/11=2 and 11/11=1)
{{{x=2*6}}}
{{{x=12}}}
