Question

а) -6 1/5: (3 2/5 - 1 1/3 ) ;                   б) - 3 2/3 * 1 1/2 - 1 2/3 * 1 1/2.

Answer 1

$a) - frac{31}{5} :( frac{47}{15} - frac{16}{15} )=- frac{31}{5}* frac{15}{31} =-3$

$b) - frac{11}{3} * frac{3}{2}- frac{5}{3} * frac{3}{2} =- frac{11}{2} - frac{5}{2} =-8$

Answer 2

A)-6 1/5: (3 2/5-1 1/3)= 3 2/-1 1/3=17/5-4/3=31/15

-31/5:31/15=-31/5:15/31=-5

B)-3 2/3 * 1 1/2- 1 2/3 * 1 1/2=-11/2*3/2=-11/2

5/3*3/2=5/2

-11/2-5/2=-16/2
