Answer 2

Answer:

$Let \: x \: be \: added \: to \: 12 \frac{4}{5} \: to \: get \: 15 \frac{2}{3} .$

Then,

$12\frac{4}{5} + x = 15\frac{2}{3} \\ \\ \frac{64}{5} + x = \frac{47}{3} \\ \\ x \: = \frac{47}{3} - \frac{64}{5} = \frac{47 \times 5 - 64 \times 3}{15} = \frac{235 - 192}{15} = \\ \\ \frac{43}{15} = 2 \ \frac{13}{15}$

Hence the required number to be added

$= 2 \times \frac{13}{15} .$
