Question

Arrange the given fractions in descending order of magnitude:
4/5, 7/15, 11/20, 3/4

Answer 1

Answer:

4/5, 3/4, 11/20, 7/15 is the decending order

Step-by-step explanation:

4/5 = 0.8

7/15 = 0.466

11/20 = 0.55

3/4 = 0.75

decending order is 0.8 > 0.75 > 0.55 > 0.466 i.e

4/5 > 3/4 > 11/20 > 7/15

or we can use the concept of equivalent fractions using the LCM of the denominators of the given fractions.

LCM of 4, 5, 15, 20 is 60

4/5 = 48/60; 7/15 = 28/60; 11/20 = 33/60; 3/4 = 45/60 (equivalent fractions)

we can compare the above fractions using the numerators

48 > 45 > 33 > 28

48/60 > 45/60 > 33/60 > 28/60

therefore 4/5 > 3/4 > 11/20 > 7/15 is the correct decending order
