1/8 < 1/6 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3

Step-by-step explanation:

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

In order to put the following fractions in order from least to greatest, we need to take the LCM of the fraction so that all the fractions have the same denominator.

1/8, 2/5, 3/5, 1/6, 1/4, 2/3, 1/3

Since the LCM of 3, 4, 5, 6, and 8 is 120. Therefore, the fractions can be written as,

1/8 = (1/8) × (15/15) = 15/120

2/5 = (2/5) × (24/24) = 48/120

3/5 = (3/5) × (24/24) = 72/120

1/4 = (1/4) × (30/30) = 30/120

2/3 = (2/3) × (40/40) = 80/120

1/3 = (1/3) × (40/40) = 40/120

Now, the fractions can be arranged as,

15/120 < 30/120 < 40/120 < 48/120 < 72/120 < 80/120

Rewriting the fraction in there original form,

1/8 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3
