There are so many ways that you can convert a fraction into a decimal, a way that I do it is by doing division. When their is a fraction, I would put the numerator inside the box so it could be the numerator divided by the denominator. Converting this can be really easy because a way you can do t is by dividing the fractions. That is just a way that I do it. Their can be so many ways though.
         For an example is that say that you have four fifths, so he you will divide 5 by 4 then you will go to the decimal places and then get .8, or it is .80. Their can be so many ways to do it, but this is a way that I do it.

Their are so many ways that you can convert decimals into fraction, a way you can do it is by having putting it over 100. If you have a number that is less than 100, you can get it by putting it over 100, but if it is over 100, you will have it over 1000, or more if it is a bigger number. Their are so many other way that you can convert them, thy can be also really easy.
   If had a decimal like .50, it can be really easy, you can already tell that it is 1 half, but can also do .50 over 100, then it will 1/2 their is so many things that you can do to change a decimal into a fraction.

An equation that I know about would be y=x3/4, if I was going to plot this I will use a method would be rise over run. Say that x was 7, if I was using the slope I will start with the 7, then go up 3 , then right 4 so that I can find the next slope. Their can be so many kind of equations, their can be small, big or just easy ones, like 2+x=4.equations may seem that they are really difficult in every way, but if you understand how to do it, and learn, you figure out that it is kinda of easy.
            To figure out and equation like 12n+5=29, it can be rally easy, the things you would just have to do is that you will subtract first, then you will have to divided so that you can get the variable by itself, and then get the answer. Their are so any other kind of equations that yo can know, like you can find number line equation, or also a tale equations, theri are so many types of equations that yo can do.

If you were at a restaurant the best one to use would probably be the percent. Percent would be a whole lot better because say that you had a coupon for a discount on the bill, but you still had to add the tax and tip. The percent would be a whole lot better because you can find all the answers easier by percent. You would probably you could put all those numbers into percent then do the work.
        But when you do the ratio, you are going to have to put the number on the top, then put the 100 on the bottom since it is out of 100. You are going have to have to do all this work so you can get the answer, when it will be easier in percent. So when you want to find the total bill, it will be a lot better on percent.
