________________________________

1. 6/1 + 1/4 + 2 3/25 + 0,3

= 6 + 0,25 + 2,12 + 0,3

= 6,25 + 2,12 + 0,3

= 8,37 + 0,3

= 8,67

________________________________

2. 24/5 × 1/8

= 24/40

= 3/5

________________________________

3. 1,25 - 0,5 × 1/4

= 5/4 - 1/2 × 1/4

= 10/8 - 1/8

= 9/8

= 1 1/8

________________________________

4. 2,5 ÷ 1/4 × 1 1/5 × 20%

= (5/2 × 4) × (6/5 × 1/5)

= 10 × 6/25

= 60/25

= 2 10/25

= 2 2/5

________________________________

5. 60% + 5/6 + 1,25 - 9/10

= 3/5 + 5/6 + 5/4 - 9/10

= 36/60 + 50/60 + 75/60 - 54/60

= 107/60

= 1 47/60

________________________________

6. 2,4 × (15/6 - 75%) ÷ 2/3

= 12/5 × (15/6 - 3/4) × 3/2

= 12/5 × (60/24 - 18/24) × 3/2

= 12/5 × 7/4 × 3/2

= 252/40

= 6 12/40

= 6 3/10

________________________________

7. 35% + 2 4/5 × (0,25 × 1/5)

= 7/20 + 14/5 × (1/4 × 1/5)

= 7/20 + 14/5 × 1/20

= 7/20 + 7/50

= 35% + 14%

= 49%

________________________________

8. 4,5 - 0,5 × (3/4 - 0,25) + 4/5

= 4,5 - 0,5 × (0,75 - 0,25) + 0,8

= 4,5 - 0,5 × 0,5 + 0,8

= 4,5 - 0,25 + 0,8

= 5,05

________________________________

9. 6/5 × 1,5 + (150% + 1 1/5)

= 6/5 × 3/5 + (3/5 + 6/5)

= 18/25 + 9/5

= 18/25 + 45/25

= 63/25

= 2 13/25

________________________________

10. 1/4 + 1,5 ÷ 0,25 =

= 1/4 + 3/5 × 4

= 1/4 + 12/5

= 5/20 + 48/20

= 51/20

= 2 11/20
