hello people all around the world this is my research webpage

Today I will teach you about math. The math we are going to learn how to do ratio math problems. They are just problems that tell you how many of something there is.
Ex. 5:8 There are 5 boys out of 8 kids in the club.
It is telling you that there are 5 boys out of 8 kids which means there are 3 girls. Lets try another one. Ex.4:7 There are 4 brownies out of 7 sweets.
Lets see what you know.
Answer the problems as best as you can on a piece of paper.
  1. There are 6 picture books out of 13 magazines. What is the ratio of picture books to magazines?

  2. A truck just came to drop off 5 more magazines. What is the ratio of picture books to magazines?

  3. Five days later the librarian threw away 2 of the picture books. What is the ratio of magazines to books?
Remember to check your answers. Did you notice something? On number 3 the question was different. It asked you for the ratio of magazines to books and not books to magazines.
Answers
For number one the answer was 6:13. For number two the answer was 6:18. For number three the answer was 4:18. If you got that one right, you were really paying attention to the problem.

    These are just some websites you can go to if your still having trouble in math.
    New ways to write ratios
    Like I have mentioned earlier, you can use the colon to write a ratio. You can also write the word "to". Ex. 4:5 is supposed to be said like this. Four to five. You can also write a ratio as a fraction. For example, if the ratio is 3:4 it would look like this in fraction form. It would be three over four. Just like a fraction except it's a ratio.
    These are the ratios 1:2,1:3 and 1:4.
