They were trying to find what I equals. V=60 and R=40 and answer is 1.5 but I dont understand how they got to I= 1.5
The problem reads I=V/R but V=60 and R=40
Please help me Thank you!

I = V / R
I = 60 / 40 amps
I = 3 / 2 amps
I = 1.5 amps

Fundamental equation V = IR
Solve for I:
I = V/R
I = 60/40 = 3/2 = 1.5 amps
Other relative fundamental equations:
P = I^2R = V^2/R = IV

Ohm's Law says V=IR
Solving for I gives
I=V/R
So using your values
(60 V)/(40 ohms) = 1.5 A
I don't see what the issue is. You seem to understand the concept and you ended up with the right answer

60/40 = 30/20 = 3/2 = 1.5
divide both the numerator by 20... then it is merely a matter of converting an improper fraction to a decimal...

I is Current (in amps), V is Voltage (in Volts) , R is resistance (in Ohms).
Ohms law states voltage equals current times resistance (V=IxR).
In this example we have V and R, want to know I.
So... they solved the V=IxR equation for I to get I=V/R.
I=V/R becomes I=60/40.
I = 1.5 Amps
