Question

(4/9-3/11)×(11/4+11/3)

Answer 1

Solution : ☺☺

$(\frac{4}{9} - \frac{3}{11} ) \times ( \frac{11}{4} + \frac{11}{3} ) \\ \\ = \frac{11 \times 4 - 9 \times 3}{9 \times 11} \times \frac{11 \times 3 + 11 \times 4}{4 \times 3} \\ \\ = \frac{44 - 27}{99} \times \frac{33 + 44}{12} \\ \\ = \frac{17}{99} \times \frac{77}{12} = \frac{17 \times 7}{9 \times 12} = \frac{119}{108}$
