please​

Answer 1

Given:

$\frac{2}{3} +\frac{6}{7} -\frac{3}{14}$

For solve this question we make a pair of first two number than solve it

$=(\frac{2}{3} +\frac{6}{7} )-\frac{3}{13}$

$=(\frac{2\times7++ 6\times3}{7\times3})- \frac{3}{7}$

$=\frac{14+18}{21}-\frac{3}{14}$

$=\frac{32}{21}- \frac{3}{14}$

$=\frac{32\times14-3\times21}{21\times14}$

$=\frac{448-63}{294}$

$=\frac{385}{294}$

=1.3

Hence the answer is 1.3
