Answer 2

Answer:

4/15 < 3/10 < 2/5

Step-by-step explanation:

First, we'll take the LCM of the denominators to make them like terms = 30

4×2 / 15×2  =   8/30

3×3 / 10×3 = 9/30

2×6 / 5×6 = 12/ 30

As 8 is the smallest and 12 is the largest number...So, we'll write it in ascending order as

= 8/30 < 9/30 < 12/ 30

= 4/15 < 3/10 < 2/5
