Question

2 by 5 into minus 3 by 7 minus 1 by 6 into 3 by 2 + 1 by 14 into 2 by 5​

Answer 1

$\frac{2}{5} \times \frac{(-3)}{7} -\frac{1}{6} \times \frac{(3)}{2} +\frac{1}{14} \times \frac{(2)}{5}$

$= \frac{-6}{35} - \frac{1}{4} + \frac{1}{35}$

/* Rearranging the terms ,we get */

$= \frac{-6}{35} + \frac{1}{35} - \frac{1}{4}$

$= \frac{ -6+1}{35} - \frac{1}{4} \\= \frac{-5}{35} - \frac{1}{4}\\= \frac{-1}{7} - \frac{1}{4}\\= \frac{-4-7}{28}\\= \frac{-11}{28}$

Therefore.,

$\red { Value \:of \:\frac{2}{5} \times \frac{(-3)}{7} -\frac{1}{6} \times \frac{(3)}{2} +\frac{1}{14} \times \frac{(2)}{5}}$

$\green { = \frac{-11}{28}}$
