Question

Answer 1

a. \(\dfrac{37}{13}\)-\(\dfrac{6}{13}\)x\(\dfrac{26}{12}\)

= \(\dfrac{37}{13}\)- 1

= \(\dfrac{37}{13}\)-\(\dfrac{13}{13}\)

= \(\dfrac{24}{13}\)

b. \(\dfrac{80}{56}\)x\(\dfrac{54}{45}\)+\(\dfrac{1}{9}\)

= \(\dfrac{12}{7}\)+\(\dfrac{1}{9}\)

= \(\dfrac{108}{63}\)+\(\dfrac{7}{63}\)

=\(\dfrac{115}{108}\)

c. \(\dfrac{9}{2}\)-\(\dfrac{5}{9}\)+ 2:\(\dfrac{3}{8}\)

=\(\dfrac{9}{2}\)-\(\dfrac{5}{9}\)+ 2 x \(\dfrac{8}{3}\)

=\(\dfrac{9}{2}\)-\(\dfrac{5}{9}\)+ \(\dfrac{16}{3}\)

= \(\dfrac{81}{18}\)-\(\dfrac{10}{18}\)+\(\dfrac{96}{18}\)

=\(\dfrac{167}{18}\)
