Hello There!
The denominators are already the same therefore you don't need to work on making them the same.
Simply just subtract the numerators:
-4 - 3 = -7
The answer is - 7/5
Hope This Helps You!
Good Luck :)

this can be solve by 3 variable equation
let x be the money of luke
y money of rachel
z money of daniel
first equation
x = y + 21
second equation
x = z + 48
third equation
x + y + z = 168
solving simultaneously
x =79
y = 58
z = 31

Answer:
51
Step-by-step explanation:
24 ^2+45^2=x^2
=51
The first table : y=4x
the second table: y=1.5x
the third table: y= 1.25x
if you want help on how to do it: plug each of those equations into the “desmos” graph! from looking at those table points (x,y) you can find which equation matches the table
for instance on table one: I put y=4x into desmos then looked at graph one, I chose the point (2,8) I went to 2 on the x axis and moved my finger up 8 and that point was directly on the line meaning that table matches the equation. be sure to also do the same thing with the other points to double check!
its B because all the other ones don't make sense for the graph and you just do the slope and it is -3
