Answer 1

Answer:

$\frac{3}{126} = \frac{1}{42}$

is the answer

Step-by-step explanation:

$( \frac{1}{7} \times \frac{2}{9} ) - ( \frac{3}{14} \times \frac{1}{9} ) + ( \frac{2}{9} \times \frac{1}{14} )$

while multiplying just multiply the both numbers

$\frac{2}{63} - \frac{3}{126} + \frac{2}{126}$

2×63 is 126 so multiply 2 on both numerator and denominator

$\frac{4}{126} - \frac{3}{126} + \frac{2}{126}$

so now since all the denominators are same just add all the numerators 4-3+2 = 3 so the answer becomes

$\frac{3}{126}$

or

$\frac{1}{42}$
