The fish caught by Neetu was of weight \[3\frac{3}{4}\text{kg}\] and the fish caught by Narendra was of weight \[2\frac{1}{2}\text{kg}\]. How much more did Neetu?s fish weight than that of Narendra?

Answer:

Given, weight of fish caught by Neetu \[=3\frac{3}{4}kg=\frac{15}{4}kg\]                                                                                                        and weight of fish caught by Narendra \[=2\frac{1}{2}kg=\frac{5}{2}kg\]                                                                                                                     Difference between their weight \[=\frac{15}{4}-\frac{5}{2}\] \[=\frac{15}{4}-\frac{5\times 2}{2\times 2}\]                                                                   [\[\because \] LCM of 2 & 4 = 4] \[=\frac{15}{4}-\frac{10}{4}\] \[=\frac{15-10}{4}=\frac{5}{4}kg=1\frac{1}{4}kg\]
