$\large \: Let \: \: the \: \: number \\ \large \: that \: \: should \: \: be \\ \large \: added \: \: be \: \: x \\ \\\large \: 7 \frac{1}{3} + x = 12 \\ \\\large \: x = 12 - \frac{22}{3} \\ \\\large \: taking \: \: lcm \\ \\ \large \:x = \frac{12 \times 3}{1 \times 3} - \frac{22 \times 1}{3 \times 1} \\ \\\large \: x = \frac{36}{3} - \frac{22}{3} \\ \\ \large \:x = \frac{14}{3} \\ \\ \large \:\therefore \: x = 4 \frac{2}{3}$
