What are two methods you can use in order to convert a fraction into a decimal? There are more than two methods to convert a fraction, but we are only looking for two. One way to convert a fraction is by dividing it by how it looks. For example, if you wanted to convert the fraction 4/5, you would divide 4 by 5. Then you would get the decimal form of that fraction.
     The other way to convert a fraction into a decimal is by knowing what the conversions already are. To do it the other way you would need to know how you could use the decimals to make the percentages of the fraction or the percentage. For example, say you got the answer of 4  divided by 5, whatever the answer is, it should be in decimal. Once that has happened, you would just add a percentage sign and you would get the percent.

What is a ratio? A ratio is something similar to a percentage but instead it look like a fraction. Percentages come from fractions so they relate very closely. The ratio can be formed in three different ways, like the fraction, with a decimal or just a plain number. A percentage is only a number which signifies how much of something is there or not there. 
     We came to choose out which would be better to deal with, ratio or a percentage? We would have to figure out which would be better to use when you're at a restaurant or at the food store buying food. At one of those moments I think that the percentage would be a better way of figuring out which one cost less and it could help you because if you had the ratio you could be confused on which way you want it to look. That way it's better to keep it simple and use a percentage.
