Question

11/9 + 7/6 . ( 2 - 1/3)

b, 20,17 . 43 + 57 .20,17

Answer 1

a) \(\dfrac{11}{9}+\dfrac{7}{6}.\left(2-\dfrac{1}{3}\right)=\dfrac{11}{9}+\left(\dfrac{7}{6}.\left(2-\dfrac{1}{3}\right)\right)=\dfrac{11}{9}+\left(\dfrac{7}{6}.\dfrac{5}{3}\right)\)

\(=\dfrac{11}{9}+\dfrac{35}{18}=\dfrac{22}{18}+\dfrac{35}{18}=\dfrac{22+35}{18}=\dfrac{57}{18}=\dfrac{19}{6}\)

b) \(20,17.43+57.20,17=20,17\left(43+57\right)=20,17.100=2017\)

Answer 2
