Question

While on their morning walk, Mr Sharma, Mr Verma and Mr Saxena walked for an equal time. The distances walked by them are exactly

3.25 km, 2.75 km

and

3 km

, respectively. Find the simplest ratio of distances covered by them. Do you go for a walk in the morning?

Accepted Answer

The ratio of distances walked by Mr Sharma, Mr Verma and Mr Saxena is $3.25 km : 2.75 km : 3 km$

$= 3.25 : 2.75 : 3$

$= \frac{325}{100} : \frac{275}{100} : 3$ [Convert the decimal numbers into fractions]

$= (\frac{325}{100} \times 100) : (\frac{275}{100} \times 100) : (3 \times 100)$ [Multiplying both the precedent and antecedent of a ratio by the same number do not change the ratio]

$= 325 : 275 : 300$

$= \frac{325}{25} : \frac{275}{25} : \frac{300}{25}$ [While changing a given ratio in the simplest form, we divide the terms of the ratio by their HCF]

$= 13 : 11 : 12$

Therefore, the simplest ratio of distances walked by Mr Sharma, Mr Verma and Mr Saxena is $13 : 11 : 12$ .
