We set up the problem first.
5/6 + 5/8 - 1/2.
We would first find a common denominator. It is 24.
Then we see how many times can 24 go into 6, 8, and 2.
We make them into improper or regular fractions, and we subtract regularly.
20/24 + 15/24 - 12/24 = 23/24.
So your answer would be 23/24.
Hope this helps☻

Answer: 15 crocodriles
Step-by-step explanation:
We know that the ratio is 4:3
This means that for each 4 hippos, we have 3 cocodriles.
We know that there are 20 hippos.
How many groups of 4 hippos we have?
n = 20/4 = 5
So we have 5 groups of 4 hippos, this means that we also have 5 groups of 3 crocodiles, then we have:
3*5 = 15 crocodiles
Because an octagon consists of eigth sides/edges, and 360 degrees is the total sum of the angles, we simply divide 360 by 8:
360/8 = 45.
Option A, 45 degrees
