Answer 2

Answer for

         (a) 1/2 + 3/10 ÷ 3/5 - 1/3 × 5/2  

              = (10 + 6)/20 ÷ 3/5 - 5/6

              = 16/20 ÷ (18 - 25)/30

              = 4/5 ÷ -7/30

              = 0.8 ÷ -0.23

              ⇒ -3.478

       (b) 4/5 ÷ 10/15 of 9 3/5

              = 0.8 ÷ 0.6 × 18.6

            ⇒ 24.8

       (c) 1/3 of 4/5 + 5/7 of 1 17/25

             = (1/3 × 4/5) + (5/7 × 117/25)

              = 4/15 + 585/175

              = 0.26 + 3.34

              ⇒ 3.6
