please help me in this ​

Answer 1

Answer:

1. 9/15

2. 3

3. 15/25

4. 9/8

5. 19/17

Step-by-step explanation:

6. LCM of 2,3 & 9 is 18. So, we have to replace all denominators by 18.

8/3=8×6/3×6=48/18

5/2=5×9/2×9=45/18

15/9=15×2/9×2=30/18

Therefore, we got after arranging in ascending order

15/9, 5/2, 8/3

7. a) 4/10 b) 1/2 c) 18/27 d) 16/24

8. 2/5 + 3/4 = (2×4+3×5)/20 = (8+15)/20 = 23/20

9. 26/3-13/5= (26×5-13×3)/15 = (130-39)/15 = 91/15 = 6 1/15

10. LCM of 4,8,12 & 24 is 24. So, we have to replace all denominators by 24.

3/4 = 3×6/4×6 = 18/24

5/12 = 5×2/12×2 = 10/24

7/8 = 7×3/8×3 = 21/24

11/24 = 11×1/24×1 = 11/24

Therefore, we got after arranging in decending order

7/8, 3/4, 11/24, 5/12
