What number is 24% of 75
maria [59]
Remember that a percentage means "parts out of 100".  24% in decimal form is therefore 0.24, because it is 24 out of the possible 100, or 1.0.  To find 24% of 75, you just multiply 0.24 times 75:

75 x 0.24 = 18

</u>                                                 825.75
<u>
