Answer:

40:15 = 8:3

Step-by-step explanation:

This is the answer because:

1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:

40 ÷ 5 = 8

15 ÷ 5 = 3

8:3

Therefore, the answer is 8:3.

Hope this helps! :D

Andrej [43]

Answer:

Minimum - 46.4

First quartile - 48.8

Third quartile - 53.2

Median - 50.4

Maximum - 55.9

Step-by-step explanation:

If you write all the numbers down on a piece of paper and start crossing out from the beginning and end Ex. cross out 46.4 and 55.9 until you get to the middle (median) thats how you figure the median out. Continue to do that until you find the first quartile, and last quartile. The maximum and minimum are easy to find those are the biggest and smallest number in the group. To find the first and last quartile, you would do the same thing to find the median just do it from the median and go to the beginning or the end depending on which one you find first. Hope this helps! I learned how to do the crossing things from my old school :)
