6. 5 7/15 x 7/5 ÷ 4/3
82/15 x 7/5 ÷ 4/3
574/75 x 3/4
574/100 = 5 74/100= 5 37/50

7. 10 12/24 ÷ 2 15/20 x 2/3
10 1/2 ÷ 2 3/4 x 2/3
21/2 ÷ 11/4 x 2/3
21/2 x 4/11 x 2/3
84/11 x 2/3 = 168/33 = 5 3/33 = 5 1/11

8. 0.75 ÷ 32/48 x 7/6
75/100 ÷ 32/48 x 7/6
3/4 ÷ 2/3 x 7/6
3/4 x 3/2 x 7/6
9/8 x 7/6 = 63/48 = 1 15/48 = 1 5/16

9. 4 2/15 + 2/6 - 3/5
62/15 + 1/3 - 3/5
62/15 + 5/15 - 3/5
67/15 - 3/5
67/15 - 9/15 = 58/15 = 3 13/15

10. 3/12 x 78.000= 19.500
