Answer:

1. Side length to perimeter = 1:4

2. Perimeter to side length = 4:1

Explanation:

Ok, so ratios are basically a way to compare two things.

For example, if someone askes the ratio of boys to girls in Mrs. White's class. Say there are 12 boys and 9 girls.

boys to girls = 12 to 9

That's a ratio!

Ratios are typically written like "12 to 9" (with the word "to") or "12:9" (with a colon) but there are also other ways.

In THIS question, you have to find the ratio of side length to perimeter and then vice versa. So, we see that the first number listed for side length is 6, and the first number for perimeter is 24. As we look down the chart, we should notice a pattern- the perimeter is 4 times as much as the side length! Therefore, the ratio of side length to perimeter is 1:4. To find the ratio of perimeter to side length, we just switch the order of the numbers. Now it's 4:1.

There! It's pretty simple! You just are finding the unit ratio!

If you need any more help, let me know! :)

The first one is 1:4 and the second is 4:1.

All there is to do is simple division (or simplifying). In the first set of two numbers side length is 6 and perimeter is 24. So if it's side length to perimeter then 6 to 24 which can be simplified to 1 to 4 and just switch the numbers with perimeter to side length.
