multiply whole equation by 5
2 +5/4t = 1
then, multiply whole equation by 4
8+5/t=4
5/t=4-8
5/t= -4
t = (-5/4) or -1.25

2/5 + 1/4t = 1/5 t=?
First subtract 2/5 from both sides => (-2/5) 2/5 + 1/4t = 1/5 - 2/5 = 1/4t = (-1/5)
Then divide (1/4) from both sides = (4/1) 1/4t = (-1/5)(4/1)
t = (-4/5)
Then plug (-4/5) back in for t and check your anwser.

multiply your denominators 4x5=20 now multply each fraction by 20 2/5 x 20=8 1/4t x 20= 5t 1/5 x 20= 4.
now add those and solve for t
8 + 5t = 4
5t= -4
t= -4/5
t= -.80 or -80%

2/5+1/4t=1/5
Multiply 20 to all figures
8+5t=4
8-8+5t=4-8
5t=-4
t=-4/5

Multiply both sides to by 20t to get rid of the denominator, which gets you...
8t+5=4t
Subtract 4t from both side, which gets you
5= -4t
Divide both sides by -4...
t= -5/4

you subtract the 2/5 over to the other side and then divide by 4/5
-4/5=t
