How do I solve this problem without calculator? I keep coming up with 270 but the calculator says 275
Thirty-three is 12% of what number?
0.12n = 33
n = 33/0.12
n = 275
33 = .12 x
x = 33/.12 = 3300/12
well
3300/10 = 330
3300/11 = 300
so I would do what you did and say 300-30 = 270
which is not a bad estimate, off by 5.
(5/275) *100 = 1.8 percent
Of course you could be more accurate with long division.
To solve this problem, you can set up an equation and solve for the unknown number.
Let's call the unknown number "x".
According to the problem, 33 is 12% of x.
To express 12% as a decimal, divide 12 by 100: 12 / 100 = 0.12.
Now, we can set up the equation:
0.12x = 33
To isolate x, divide both sides of the equation by 0.12:
x = 33 / 0.12 = 275
Therefore, the number you are looking for is 275.
