To find what percent a part is of the whole, divide the part by the whole and multiply by 100.

Part: 18
Whole: 45

percent = part/whole * 100

percent = 18/45 * 100 = 2/5 * 100 = 0.4 * 100 = 40

18 is 40% of 45.

Hey there!

[tex]Write \ 45 \ as \frac{45}{100} \\ \\ Since, \ finding \ the \ fraction \ of \ a \ number \ is \ same \\ as \ multiplying \ the \ fraction \ with \\ the \ number, \ we \ have....... \\ \\ \left[\begin{array}{ccc} \left[\begin{array}{ccc} \boxed{\boxed{\frac{45}{100} \ of \ 18= \frac{45}{100}*18=8.1 }} \end{array}\right] \end{array}\right] [/tex]

Hope this helps you! :)
