Question:

Simplify using distributive property:
(79)(67−34). [Page No. 49]\left(\frac{7}{9}\right) \left(\frac{6}{7} - \frac{3}{4}\right). \text{ [Page No. 49]}

Answer: Verified

(79)(67)−(79)(34)\left(\frac{7}{9}\right)\left(\frac{6}{7}\right)-\left(\frac{7}{9}\right)\left(\frac{3}{4}\right)

=4263−2136= \frac{42}{63} - \frac{21}{36}

=23−712= \frac{2}{3} - \frac{7}{12}

=812−712=112= \frac{8}{12} - \frac{7}{12} = \frac{1}{12}
