Arrange 1/5 3/4 7/8 And 1/2 In Descending Order

Arranging Fractions in Descending Order: 1/5, 3/4, 7/8, and 1/2

To arrange the fractions 1/5, 3/4, 7/8, and 1/2 in descending order (from largest to smallest), we need to find a common denominator. Here's how:

1. Finding the Least Common Multiple (LCM) of the denominators:

The denominators are 5, 4, 8, and 2. The LCM of these numbers is 40.

2. Converting each fraction to an equivalent fraction with the denominator of 40:

  • 1/5: Multiply both numerator and denominator by 8: (1 x 8) / (5 x 8) = 8/40
  • 3/4: Multiply both numerator and denominator by 10: (3 x 10) / (4 x 10) = 30/40
  • 7/8: Multiply both numerator and denominator by 5: (7 x 5) / (8 x 5) = 35/40
  • 1/2: Multiply both numerator and denominator by 20: (1 x 20) / (2 x 20) = 20/40

3. Arranging the fractions in descending order:

Now that all the fractions have the same denominator, we can easily compare their numerators:

  • 35/40
  • 30/40
  • 20/40
  • 8/40

Therefore, the fractions arranged in descending order are:

7/8, 3/4, 1/2, 1/5
