To order the fractions from least to greatest (ascending order), you can follow these steps:

1. Find a common denominator for all the fractions.

The denominators in this case are 10, 20, and 5. The least common multiple (LCM) of 10, 20, and 5 is 20. Multiplying the fractions by the appropriate factors will give them a common denominator of 20.

2. Rewrite the fractions with the common denominator.

7/10 = 14/20 (multiply both numerator and denominator by 2)
9/20 = 9/20 (no change needed)
4/5 = 16/20 (multiply both numerator and denominator by 4)

Now we have the fractions as 14/20, 9/20, and 16/20.

3. Compare the numerators to determine the order.

Since the denominators are now the same, we can focus on comparing the numerators. The fractions with smaller numerators will be lesser in value.

So, the order of the fractions from least to greatest:
9/20 < 14/20 < 16/20
