Important Math

                The most important math I think will be useful in life is addition, subtraction, multiplication, and division. Why? Because when you buy something, someone purchases it you have to know how to count, because if you don't you might get into trouble. That is mostly important to cashiers at stores and stuff.
Another important math we might need is Decimals to fractions because, it's like getting a price off. You have to know your discounts when you get older so you know whether you need more amount of money or less so you can save things up when your older.
When you go to the bank, some people don't know how to save their money so you can use math to know how much money you have in your bank, so you won't use it all. Because y mom does that, we have a lot of money but still, the more money the better. 

Some people use fractions to figure out things, like for example how much people ate a pizza and how much is left to eat with out looking at the pizza. You can also turn it into a fraction which tells how many percents have it, you can turn a fraction to a decimal, from a decimal to a fraction. It's very simple.

Fraction -----> Decimal

                           To convert a fraction into a decimal, You can use two methods which are dividing the fraction, Like laying it to the side and diving it and whatever you get you can turn it into a decimal. I prefer that because it is more easier, and everybody learns it like in sixth or fifth grade. It is easy. What I don't prefer is reducing it and then finding the whole and then simplify it. It is harder like that. So most of all I prefer to use flip it and divide it, when you lay it on the side because it is more easier like that. Sometimes people use calculators, which make it a little harder because then you have all these numbers, and it's just confusing and you don't know what to do with it, that's how most people mess up and problems like that.
           Some people use that, but when people challenge theirselves, they use the harder way of solving the Fraction into a decimal. Which is more likely to be complicated for most people, the  one method I told you about is more reliable, and everyone knows right that it's better than the other method, Well I don't prefer better but like it is more easier and faster to solve and every kid learns it at a young age.

Ratio or Percentage?

                   If I were to choose between ratio or percentage for a fast food resturaunt to pay the exchange. I would choose percentage because it's better and understanding. Ratio, I wouldn't choose because If you do choose ratio, It's more harder and slower to solve. Some people don't even know how to use it. Percentage, you get a better of understanding because you can actually estimate how much your either paying or receiving. When you have a percentage, I can be better and you can also solve it quicker. For example if it were fifty percent, you would estimate that you should be paying about half the price you should be paying. It's like discount. I'm just saying, If I were to choose to use ratio between the percentage, I would already choose percentage with a snap of a finger.
                    Some people would choose the ratio because it's more advanced, some people would use it though. The best thing to know is that ratios may not be solved on the computer the way percent can, because in restaurants, computers are always used in restaurants when it comes to someone having to pay the price. Ratios are most of the time solved on peaper, waiters probably do the but I don't think so by the way. So when you go to a restaurant, ask someone that is the cashier there if they would rather use ratio or percentage to pay there?
