The answer is 1/16.
When it comes to fractions, it's quite simple! If you can multiply, you can do this!
Simply write the the top number over the bottom so it looks normal. Multiply straight across. 1x1 is 1, and 8x2 is 16. Don't do anything else! It's 1 over 16 OR 1/16
You can add the numbers together so:
12.6
3.1
<u>+ 5.4
</u> 21.1
<u>
</u>Since the sum of the numbers is 21.1, it is greater than 20<u>
</u>
255/56 = 4.55....
You can't have 0.55... buses so you round that up to 1.
Therefore 4+1 = 5 so 5 buses would be the minimum.
It is a right triangle. If it contains the 90°, it is definitely a right triangle.
