If the container is divided into 12ths you should make that your common denominator.
So 1/4 now equals 3/12
Since we want this 3/12 to be empty we must subtract it from 12/12 leaving us with 9/12.
When we subtract 2/12 from 9/12 to get the amount that was already filled we get 7/12 which is the amount that needs to be filled.
To check we add our parts 2/12 and 7/12 to get 9/12 which is 3/4 of the container filled leaving 3/12 or 1/4 of the container empty.
Hope this helps ☺
11b. Is the answer. Okokok
Thus, the rate of change per gallon of gas is 60 miles per gallon.
A motorcycle consumes 5 gallons of gas for 300 miles and 7 gallons for 420 miles.
<h3>What is
rate of change?</h3>
Rate of change is defined as the change in value with rest to the time is called rate of change.
Now,
Rate of change = Difference B/w volume (i.e. in gallons) /difference in miles
= 420-300/7-2
= 60 gallons/mile
Thus, The required rate of change per gallon of gas is 60 miles per gallon.
