17.16 is 62.4% of what number?

'is' indicates an equal sign.

62.4% = 0.624

'of' indicates multiplication

'what number' indicates an unknown value that we can call 'x'

17.16 = 0.624 * x

17.16 = 0.624x

Divide 0.624 to both sides:

x = 27.5
well first 62.4% of a number is the same as saying 624/1000 of a number so in order to calculate that you have to multiply 17.16 by 1000
17.16* 1000 = 17160
then you you have to divide it by 624
17160/ 624 = 27.5
so the answer to your question is 27.5

i hope i helped you
