I'm terrible at math, so I'm sorry if I'm totally wrong, but I'm assuming you just take the average:
20+28=48m
48/2=24m
On average, it may take them 24m if they work together.
4 5/8 as an improper fraction is 37/8
——> 8*4=32 32+5=37
As a mixed number it is the same I think. 5 can’t decide into 8 so it stays 4 5/8.
Hopefully this helps...
The number that will be immediately filled before 32754 is 32658
Option E is correct.
(86.8 - 3n)/4
You can get this by combining the two. Make sure to give common denominators.
