Question

(2−¹+3−¹+4−¹) × 3/4 = ​

Answer 1

$( {2}^{ - 1} + {3}^{ - 1} + {4}^{ - 1}) \times \frac{3}{4} \\ \\ = ( \frac{1}{2} + \frac{1}{3} + \frac{1}{4} ) \times \frac{3}{4} \\ \\ = ( \frac{(1 \times 6) + (1 \times 4) + (1 \times 3)}{12} ) \times \frac{3}{4} \\ \\ = ( \frac{6 + 4 + 3}{12} ) \times \frac{3}{4} \\ \\ = \frac{13}{12} \times \frac{3}{4} \\ \\ = \frac{13}{4} \times \frac{1}{4} \\ \\ = \frac{13}{16} \\ \\ = 0.8125$
