Question

Cost of pen is 16 2/3 and that of pencil 4 1/6.which cost is more and by how much?

Answer 1

Answer:

$cost \: of \: pen = 16 \frac{2}{3} = \frac{50}{3}$

$cost \: of \:pencil = 4\frac{1}{6} = \frac{25}{6}$

$\: lc m \: of \: 3 \: and \: 6 = 3 \times 2 = 6$

$\frac{50 \times2}{3 \times2 } = \frac{100}{6 \: } \: and \: \frac{25 \times 1}{6 \times 1} = \frac{25}{6}$

Both fraction having same denominator :

Clearly,100 is greater than 25.

$so \: 16\frac{2}{3} \: is \: greater \: than \: 4\frac{1}{6} means\: cost\\ \: of \:pen\: is \:greater \:than\: cost\: of\: pencil \\ \: by \: \frac{50}{3} - \frac{25}{6} \\ \: \: = \frac{100 - 25}{6} \\ \: \: = \frac{75}{6} \\ \: \: = \frac{25}{3} \\ \: \: = 8\frac{1}{3}$
