This is as if you cut 110 into one-hundred equal parts and find fifteen of those parts and say how much this is.

15% means highlight_green%2815%2F100%29.

Setting the question as a proportion:
15%2F100=v%2F110;
Examine that equation for a few seconds, and then read the top given description again.

You want those two fractions to be equal. As arranged, v is fifteen percent of 110. If you multiply the left member AND the right member by 110, you have v on one side and a numeric expression which you can compute on the other side. Do the computation and you have the finished value for v.

15%2F100=v%2F110
110%2815%2F100%29=110%28v%2F110%29
11%2815%2F10%29=%28110%2F110%29v
%2811%2A15%2F10%29=1%2Av=v
%2811%2A3%2A5%29%2F%282%2A5%29=v
%2811%2A3%29%2F2=v
33%2F2=v
v=16.5
