Answer 1

Answer:

=3/4-5/7-914

=7(4)-4(5)/28+9/14

=28-20/28+9/14

=8/28+9/14

=8+2(9)/28

=8+18/28

=26/28 cancal on 2

= 13/14 Ans

Answer 2

Answer:

$\large{\green{\frac{19}{28}}}$

Step-by-step explanation:

$\large \sf \: Simplify$

$\red{\frac{3}{4} - \frac{5}{7} + \frac{9}{14} }$

${ \sf \: take \: \: lcm \: \: of \: \: the \: \: denominators}$

$\sf \: LCM \: = \: 2 \times 2 \times 7 = 28$

$\sf\implies\frac{21 - 20 + 18}{28}$

$\sf\implies\frac{39 - 20}{28}$

$\huge{ \boxed {\green{ \frac{19}{28} }}}$
