= 252/(90%/100%)
= 252/(9/10)
= 252(10/9)
= 2,520/9 or 280
Answer: 280
= 252/(9/10)
= 252(10/9)
= 2,520/9 or 280

252 ÷ 90%
= 252 ÷ 90/100
= 252 x 100/90
= 252 x 10/9
= (252 x 10)/9
= 2520/9
= 280
= 252 ÷ 90/100
= 252 x 100/90
= 252 x 10/9
= (252 x 10)/9
= 2520/9
= 280

90/100 Ã X = 252
X = 252 Ã 100/90 = 280
X = 252 Ã 100/90 = 280

90% x ___ = 252
------ = 252 / 90 %
____ = 252 / 90/100
____ = 252 x 100/9
------- = 280
------ = 252 / 90 %
____ = 252 / 90/100
____ = 252 x 100/9
------- = 280

90%x = 252
x = 252/90%
x = 252/0.90 = 280
x = 252/90%
x = 252/0.90 = 280

252 divided by .9 = 280
try to remember this formula:
Percentage= Base x Rate
Base= Percentage Divided by Rate
Rate= Percentage Divided by Base

This is the easy way to look at a word problem like this. Before the steps, you have to convert the 90% to a number without the percent. All you have to do is divide the percent by 100.
90/100 = 0.9
Now, for word problems...anytime you see the word "of", it means to multiple. Anytime you see the word "is", it means equal to.
We will let x represent the number we are looking for.
Therefore, 0.9 times x = 252
0.9x = 252
Now isolate x by dividing both sides by 0.9
x = 252/0.9
x = 280
90/100 = 0.9

90/100 x A=252
A=(252)/ (90/100)=280
A=(252)/ (90/100)=280

Divide 252 into 9 parts.
So, each is 28.
Now, add 28 to 252.
= 280.
Now, check.
0.9*280 = 252.
So, that's right.
