Answer:

50

Step-by-step explanation:

use the proportion:  "Is/Of equals Percent/100"

'what is' means assign a variable

'Is Equal to' = 12

'Of What Number' means assign a variable = n

24% = 24/100

put it all together:

12/n = 24/100

cross-multiply to get:

24n = 1200

n = 1200/24

n = 50

Answer:

24% of 12 is 2.88.

Step-by-step explanation:

Let the unknown (the "what") be n.  Then 24% of n is 12.  To calculate this, convert the 24% to 0.24 and multiply 12 by it:

0.24n = 12, so n = 12/0.24 = 50

24% of 50 is 12
