Answer: 20/12
Step-by-step explanation: In order to get a 12 in the denominator
of 5/3, we multiply top and bottom of 5/3 by 4 to get 20/12.
So 20/12 is an equivalent fraction.
75x + 90(15-x)=88(15)
75x+1350-90x = 1320
-15x + 1350 = 1320
-15x= -30
x=2
the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons
