Answer:
180 miles
Step-by-step explanation:
We already know he drove 300 miles with 25 gallons of gas ;however, we dont knoe how much gallons he drives with 15 miles.
Step 1- make a grid. M/G.
M=Miles
G= Gallons.
Step 3. We know he uses 25 gallons of gas to go 300 miles so you just fill it out. Heres what you get.
300/25.
Step 3. Now you have to fill out the other side. We know he wants to use 15 GALLONS but we dont know how much miles he uses. So lets fill the rest of the chart out. Heres what we get:
?/15.
Step 4. Now that you got the chart filled out the next steps are easy! You do bat and ball. Heres how you use bat and ball.
Bat and ball:
First you make the chart (e already did that so we can move on) Now you look at the numbers
300/25
?/15
Now you circle 300 and 15. This is the BAT part. (You mainly circle the lonely number and the number diagnal from it) Now you circle the last number which in this case is 25.
For the BAT part you multiply. 300×15=4500 if you multiplied correctly.
For the BALL part you divide the answer of the BAT part with the BALL. In this case it's
4,500÷25.
If you divided it correctly you get 180.
And thats how you get the answer. There are many techniques to how to do this, but I perfer this one. Its much easier.
