Question

3pe7+2pe15-8pe35+1pe14

Answer 1

3/7+2/15-8/35+1/14
= 45/105+14/105-24/105+1/14
= 35/105+1/14
=1/3+1/14
= 14/42+3/42
= 17/42

Answer 2

$\frac{45}{105}+ \frac{14}{105} - \frac{24}{105}+\frac{1}{14 } = \frac{59}{105}-\frac{24}{105}+ \frac{1}{14}= \frac{35}{105}+ \frac{1}{14} =\frac{1}{3}+ \frac{1}{14}=\frac{14}{42} +\frac{3}{42}$
