Respuesta :

10 liters of gas fill one tank.
x liters of gas fill x/10 tanks.
35 liters of gas fills 35/10=7/2 tanks
7/2 can also be written as 3.5 or the mixed number (3 and 1/2)

Step-by-step explanation:

1 can is to 10 liters as x cans is to 35 liters.

Write a proportion:

1 / 10 = x / 35

Cross multiply:

10x = 35

Divide:

x = 3.5

It takes 3.5 cans.
