Am i correct ?

in a group of sinngle mothers, 14% were on welfare while the others were employed . if 4300 were employed, how mmany mothers in this group were on welfare?

i did this..but now i think what i did isn't right. what are your thoughts on what i did :

14/100 = x/4300
100x = 60200
x = 602
