The answer is 9 for this one
Multiply 1/5 and 26/1 across the top and bottom, and you get 26/5
From there, you can estimate that its a little more than 5 because you know that 25/5 is 5 and 26/5 should be a tiny bit greater.
Hope this helped!
She will need 1/3 cup because she has already covered 3/4
.75 is the answer because it looks like division
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
Hope this helps.
