Question

A motor racing circuit has length 5 5/6 miles.
A straight section of the circuit has length 1 1/4 miles.
What fraction of the circuit is the straight section?
Give your answer in its simplest form.

Answer 1

Total length = 5 5/6 miles = 35/6 miles
Straight section = 1 1/4 miles = 5/4 miles

The fraction of the circuit which is straight is
$\frac{1 \, 1/4}{5 \, 5/6} = \frac{5/4}{35/6} = \frac{5 \times 6}{4 \times 35} = \frac{3}{14}$

Answer: $\frac{3}{14}$

= 

Answer 2

Answer: 3/14

Step-by-step explanation:

Total length=5 5/6 miles= 35/6 miles

Straight section= 1 1/4miles= 5/4 miles

(1 1/4)/(5 5/6)=(35/6)/(5/4)=3/14
