The first question asks what is 245% of $356.80. To solve this particular question the easiest way to do so is to use a ratio chart, as shown in the image above. As mentioned previously, the question asks what is 245% of $356.80, meaning $356.80 is the whole, or 100%. That is the first thing you put is what 100% is, or the whole. Our goal is to find what 245% of $356.80 is, so the easiest way to attack this kind of question is to find what 1% is. So how do we get from 100% to 1%? We divide by 100! Remember, whatever we do to one side we must to do the other (of the ratio chart). 100% divided by 100 is 1, and 356.80 divided by 100 is 3.5680. Now that we know what 1% of $356.80 is we can easily find out what 245% is quickly, simply by multiplying 1 by 245. Quite obviously, 1 multiplied by 245 is 245, and 3.5680 multiplied by 245 is 874.16. Our answer is

**$874.16.**

The question asks what 68 3/4 of 730 is. We're using a ratio chart to solve this question. We begin with what 100% is, and divide that by 100 on both sides to find what 1% is, which in this case, is 7.3. From there we multiply 1 by 68.75 because that is the percent of we are looking for. Our answer is

**501.875**.

**$467.82.**

The question asks for the commission of a house if the house is sold for $345 000. To do that we find what 6.75% of 345 000 is. We begin our ratio chart with what 100% is, which in this case is $345 000. We divide 100% on both sides by 100 to find 1 percent, which is 3450, and multiply that by 6.75, which is 23287.5%. Our answer is

**$23287.50.**We do this because commission is what the salesmen gets off of what he/she sells. He/She gets a certain percentage (in this case 6.75) of the sales price (in this case $345 000) so that's why we solved for 6.75% of 345 000.

The question asks how much sodium is one person eating daily if people are eating 182% of 1700 mg of it. As always be begin by writing out what 100% is, which would be in this case 1700. We divide that by 100 on both sides to find 1%, which would be 17. Then we multiply that by 182 on each side to solve for our answer. Our answer is

**3094 mg**. We do this because 1700 mg is what is recommended about, and what people are usually taking in is 182% of this. Our goal was to find 182% of that because that's what people were taking in.
