Answer:

2.5 gallons of gas

Explanation:

Note : we have a proportional relationship between the two variables

_______________________________________

He used 3/4 gallon of gas to mow 3/10 of the lawn

Then

He has to use 1/4 gallon of gas in order to mow 1/10 of the lawn

( we divided both sides by 3)

Then

He has to use 10 × 1/4 gallons of gas to mow 10/10 of the lawn

What that means is :

He has to use 10/4 gallons of gas to mow the entire lawn

In other words :

He has to use 2.5 gallons of gas to mow the entire lawn
