Question

$4 \times \frac {2}{6} - 2 \times \frac{2}{8} + 3 \times \frac{7}{12}$
​

Answer 1

$4 \times \frac{2}{6} - 2 \times \frac{2}{8} + 3 \times \frac{7}{12} \\ \\ \frac{4}{3} - \frac{1}{2} + \frac{7}{4} \\ \\ \frac{16 - 6 + 21}{12} \\ \\ \frac{31}{12}$

Answer 2

Answer:

4×2/6-2×2/8+3×7/12

=4/3-2/4+7/4

=4/3+(7-2)/4

=4/3+5/4

=(4×4+5×3)/12

=(16+15)/12

=31/12

=2 7/12
