1) 56/84

= 2/3

2) 3/5

= 3 ÷ 5

= 0,6

3) 2/5(30%)

= 2/5(30/100)

= 2(30)/5(100)

= 60/500

= 3/25

4) 2 1/8 - 1 5/12

= 17/8 - 17/12

= (17 × 3)/(8 × 3) - (17 × 2)/(12 × 2)

= 51/24 - 34/24

= 17/24

5) 6/9 ÷ 2/3

= (6 ÷ 2)/(9 ÷ 3)

= 3/3

= 1

6) 25/45 ÷ 5/5 ÷ 5/9

= (25 ÷ 5)/(45 ÷ 5) ÷ 5/9

= 5/9 ÷ 5/9

= (5 ÷ 5)/(9 ÷ 9)

= 1/1

= 1

7) 17/20

= (17 × 5(/(20 × 5)

= 85/100

= 85%

8) 2 1/6 + 1 3/4

= 13/6 + 7/4

= (13 × 2)/(6 × 2) + (7 × 3)/(4 × 3)

= 26/12 + 21/12

= 47/12

= 3 11/12

9) 45/68 × 17/15

= (45 × 17)/(68 × 15)

= 765/1020

= 3/4

10) 0,35

= 35/100

= 35/5/100/5

= 7/20
