1747 + 13212 - ? = 1123

17 4 7 + 13 2 12 - ? = 11 2 3 123 7 + 158 12 - ? = 35 3 => ? = 123 7 + 158 12 - 35 3 => ? = 1476 + 1106 - 980 84 => ? = 19.07

Correct Answer: 19

Explanation:

$17 \frac{4}{7} + 13 \frac{2}{12} - ? = 11 \frac{2}{3}$

$\frac{123}{7} + \frac{158}{12} - ? = \frac{35}{3}$

=> $? = \frac{123}{7} + \frac{158}{12} - \frac{35}{3}$

=> ? = $\frac{1476 + 1106 - 980}{84}$

=> ? = 19.07
