Answer: 3/14
Step-by-step explanation:
From the question, we are informed that a motor racing curcuit has length of 5 5/6 miles and a straight section of the curcuit has length of 1 1/4 miles.
To calculate the fraction of the curcuit that is the straight section m, we divide 1 1/4 miles by 5 5/6 miles. We need do convert the fractions to improper fraction first. This will be:
1 1/4 = 5/4 and 5 5/6 = 35/6
This will then be:
= 5/4 ÷ 35/6
= 5/4 × 6/35
= 30/140
= 3/14
