(b) 1/3 3/7 7/10 13/28​

Answer 1

Answer:

7/10> 13/28> 3/7> 1/3

Step-by-step explanation:

LCM of 3, 7, 10 and 28 i.e., LCM of the denominators

3 = 3×1

7 = 7×1

10 = 5×2

28 = 7×2×2

So, LCM = 2×2×2×3×5×7

= 840

1/3 = 1×280/3×280 = 280/840

3/7 = 3×120/7×120 = 360/840

7/10 = 7×84/10×84 = 588/840

13/28 = 13×30/28×30 = 390/840

Arranging in descending order

= 588/840> 390/840> 360/840> 280/840

= 7/10> 13/28> 3/7> 1/3
