Question

A boat can travel 412 miles on 103 gallons of gasoline. How much gasoline will it need to go 184 miles?

Answer 1

Hey there! I'm happy to help!

Let's set this up as a proportion (2 equal ratios).

`(miles)/(gallons) =(412)/(103) =(184)/(g)`

If you multiply the diagonal numbers, their products will be equal. (412×g=103×184). This is called cross multiplying. Now we can solve for g.

412g=18952

Divide both sides by 412.

g=46

Therefore, the boat will need 46 gallons of gasoline to go 184 miles.

Have a wonderful day! :D
