24% of what is equal to 12

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

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

why can't you?

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
