It means that a player had 5 official At Bats in the game (or some other timeframe) and got 4 Hits. That wouldn't include walks, sacrifices, or other types of plate appearances that don't count as an official At Bat.

It means 1:1.
if you mean (4/1)/8 it would be 4/8 = 1/2 but if you mean 4/(1/8) it would = 32
The mean is the arithmetic average. The average of 4 9 7 4 & 1 is 5
If you mean 1/4+3/4, that equals 1 or 1/1.
If you mean (4, -1) and (-1, 4) Slope: (-1-4)/(4--1) = -1
If you mean (4, -1) and (-1, 4) Slope: (-1-4)/(4--1) = -1
Do you mean 4 times 1/4. If so the answer is 1.0 Or do you mean 1/4 of 1/4. Then the answer is 0.0625

If you mean: 0.25 then it is 1/4 but if you mean 025 then it is 25/1
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1
4-1 = 3 perhaps you mean 4 minus negative 1? 4 -(-1) = 5
