Least to greatest 2/4...2/3..2/8..2/6

Change them either to decimals or fractions with the same denominator.

Example:
2/4 = 12/24 = 0.5

2/4 = 12/24.

2/3 = 16/24.
2/8 = 6/24.
2/6 = 8/24.
Put them order.

To arrange the fractions from least to greatest, we can compare their values by looking at their denominators and numerators.

First, let's simplify the fractions:

2/4 = 1/2 (both the numerator and the denominator can be divided by 2)
2/3 remains as it is (cannot be simplified further)
2/8 = 1/4 (both the numerator and the denominator can be divided by 2)
2/6 = 1/3 (both the numerator and the denominator can be divided by 2)

Now, let's order them from least to greatest:

1/4, 1/3, 1/2, 2/3

So, the fractions arranged from least to greatest are 1/4, 1/3, 1/2, 2/3.
