What percent is 72 of 120???
[tex]120*x\% = 72 \\ \\ \\ 120* \dfrac{x}{100} = 72 \\ \\ \\ \dfrac{x}{100} = \dfrac{72}{120} \\ \\ \\ x= \dfrac{72}{120} * 100\qquad \to \boxed{x= 60\% } [/tex]
60% *120 = 72
0,6 *120 = 72
72 = 72
I wish you much success in your studies!!!!

Well, first you set up a proportion. x/100 = 72/120 (remember is over of) and you cross multiply. 100 x 72= 7200. 120x=7200. Then you divide both sides by 120, and you get 60%
