     Hello and welcome to Math Monday! Today I will be attempting to write about converting fractions into decimals. It seems simple... and it is. One way to convert a fraction into a decimal is to divide. Here is a great example....

1/2 is our fraction... but we want a decimal. So we are going to divide...
1 divided by 2. Since one is smaller than 2 your answer has to be a decimal. .50 to be exact. Another way is to have  a ratio... let's say for every 1 banana we get to slices of banana bread. 1:2. Now you can divide... 1 divided by 2. Again, since 1 is smaller than 2 you should get a decimal... .50, again.


     If you don't understand somethings it is completely okay to talk to your teachers because they are there to help you. There are also tons of books for math if something doesn't make sense. Don't give up because that gets you nowhere. Stay pro-active!!!

Ratio and Pecentages and, well... Food

     Imagine you work at a restaurant, the best one in town! That means your restaurant is popular, and food disappears very quickly. Your boss hired you to make daily trips to the nearby supermarket and  replace food. He sways you could use percentages or ratios for each meals ingredients, but expects you to be back in 3 hours. Can you do it?
     A percentage is like a decimal and a fraction which if your buying things... could be tricky to use. A ratio would be easier. Here's an example. On the dessert menu, banana bread is a popular option. 1 banana is used for every piece of banana bread baked. That means 1 banana is used in every loaf of banana bread... 1:1. A ratio would be easier to buy things. 10 bananas will give you 10 loaves of banana bread. If 4 grapes make glass of grape juice, 4:1, then how many would grapes would be used to make 4 glasses of grape juice. 16 grapes! Let's say you need 1 ounce of cheese for a small bowl of kids' macaroni and cheese. You buy 15 ounces of cheese! That means 15 bowls of kids macaroni will be served!
     As you can see, working in a restaurant can be tough. Working with ratios, well, that can be as easy as you make it! Just remember... 1:1 or 1 to 1.... are a couple different types of ratio formulas and all you have to do it look for the numbers then plug them in! Good luck!
