Question

the height of deepak and vikas are 3 4/5 cm and 7 1/4 cm respectively who is taller and by how much​

Answer 1

Answer:

Vikas is taller by 3 9/20 cm.

Step-by-step explanation:

We know that 3⅘< 7¼

For the difference :

$7 \frac{1}{4} - 3 \frac{4}{5} \\ = \frac{(7 \times 4) + 1}{4} \ \ - \: \frac{(3 \times 5) + 4}{5} \\ = \frac{28 + 1}{4} - \frac{15 + 4}{5} \\ = \frac{29}{4} - \frac{19}{5} \\ = \frac{29 \times 5}{4 \times 5} - \frac{19 \times 4}{5 \times 4} \\ = \frac{145}{20} - \frac{76}{20} \\ = \frac{145 - 76}{20} \\ = \frac{69}{20} \\ = 3\frac{9}{20}$
