25% of 1/6 = 0.25 * (1/6) = (1/4)*(1/6) = 1/24

Add this to 1/6 to get 1/6 + 1/24 = 4/24 + 1/24 = 5/24

So the fraction going to rent is 5/24

The fraction going to the car payment is 1/6 (given)

Add the two fractions: 1/6 + 5/24 = 4/24+5/24 = 9/24 = 3/8

=======================================================

Final Answer: 3/8

car payment=C= 1/6 S=S/6
rent =R= 1.25 C
C+R=(1/6)S+(1.25/6)S
C+R=(2.25/6)S
C+R==(225/600)S
C+R=(3/8)S
