Answer: C. 2 x 2 x 2 x 2 x 5
Step-by-step explanation: if you multiply all of those numbers you get 80
X - ( 1 / 2 )x - ( 1 / 3)x = 6x / 6 - 3x / 6 - 2x / 6 = ( 1 / 6 )x, where x is full tank of gas
The answer is 1 / 6 of the gas have left ;
I completely agree with the above statement
x/20 = 21/14 (similar proportions)
x/20 = 3/2 (simplify by canceling out a factor of 7)
x = 30
