The answer has to be A. Half of 350 is 175 and half of that is 85. Therefore, it can only be 3%. But for an exact number all you have to do is divide 12 into 342 and multiply by 100.

Let's work it out:
X= what percent
of means to multiply
is means equals
So...
342X = 12 or
X = 12/342 so
X = 0.0351
You must multiply this answer by 100 to get the percent
100 x 0.0351 = 3.51%
So the answer is A
If you want to check your answer think this way....
What is 10% of 342? 34.2
So 5% is half of that amount or 17.1
Half of 5% is 2.5% which is half of 17.1 or 8.55
So our answer is realistic. Because 12 is between 17.1 and 8.55 just as 3.5% is between 5% and 2.5%. Okay that may have been confusing :>)

1200 divided by 342...The answer is A. You set up a ratio and then you cross multiply and divide. You make the fraction x over 100 times 12 over 342. Then like I said U cross multiply and divide. Don't worry. After U do a few of them it gets easier!
