Captain salamander goes on a long journey around the world. He travels 1/4 of the journey by plane, and the rest by boat. What fraction of the journey does he travel by boat?
Answers
Concept
We will consider that the total journey around the world is represented by 1. And then subtracting the fraction of journey travelled by the plane from the journey around the world will give the value of the fraction of journey travelled by the boat.
Given
The journey travelled by plane is 1/4.
The total journey around the globe is 1.
Find
We are asked to calculate the fraction of the journey travelled by the boat.
Solution
Journey around the world = Journey travelled by the boat + Journey travelled by the plane
Journey travelled by the boat = Journey around the world - Journey travelled by the plane
Journey travelled by the boat = 1 - (1/4)
Journey travelled by the boat = 3/4
Hence the fraction of the journey travelled by the boat is 3/4.
