Arrange the following fraction to least to greatest.4/5,1/2,1/4.

Least Common Denominator = 20

4/5 = 16/20
1/2 = 10/20
1/4 = 5/20

now arrange them

4/5 1/4 1/2

To arrange fractions from least to greatest, you need to compare their values. One way to do this is by finding a common denominator for all the fractions.

Let's find a common denominator for 4/5, 1/2, and 1/4.

The smallest common denominator we can find is 20 because it is divisible evenly by 5, 2, and 4.

Now, let's change each fraction to have a denominator of 20.

4/5 = 16/20 (multiply the numerator and denominator by 4)
1/2 = 10/20 (multiply the numerator and denominator by 10)
1/4 = 5/20 (multiply the numerator and denominator by 5)

Now that we have a common denominator of 20 for all the fractions, we can compare their numerators.

5/20 is the smallest fraction.
10/20 is greater than 5/20 but less than 16/20.
16/20 is the greatest fraction.

So, the fractions arranged from least to greatest are:
1/4, 1/2, 4/5.
