Question

Tora took a short trip of 320 miles. He stopped to have lunch after he had driven 120 miles. Write the fraction of the trip he had completed by lunch in simplest form. Then write the fraction as a decimal.

Answer 1

The fraction of the trip completed is ³/₈

The fraction of the trip completed in decimal form is 0.375

Explanation:

Given;

total trip to be completed by Tora, = 320 miles

distance completed by Tora, = 120 miles

The fraction of the race that Tora has completed is given as;

`= (distance \ completed)/(total \ distance) \\\\= (120)/(320)\\\\= (12)/(32) \ (divide \ both \ numerator \ and \ denominator \ by \ 4)\\\\= (3)/(8)`

As a decimal the fraction is written as;

`(3)/(8) = 0.375`
