Answer 1

Question :-

Rahul got 34 marks out of 50 in maths and Praful got 14 marks out of 20 marks in maths. whose performance is better-?​

Answer :-

Given :-

Rahul's Mark = $\frac{34}{50}$
Praful's Mark = $\frac{14}{20}$

Here, The denominators are different. So, Let's find the LCM and find which greater.

LCM of 50 and 20 = 100

Rahul's Mark = $\frac{34}{50} * 2 = \frac{68}{100}$
Praful's Mark = $\frac{14}{20} * 5 = \frac{70}{100}$

Comparison :-
$\frac{70}{100} \geq \frac{68}{100}$

Conclusion :
Therefore, Praful's Performance in maths is better.
