For fractions comparison, the denominators of given fractions must be equal to each other. If not, find the LCD and compare the fractions.
Find the LCD of fractions 4/9 and 5/8.
Factors of 9 = 3 x 3
Factors of 8 = 2 x 2 x 2
LCD = 2 x 2 x 2 x 3 x 3 = 72
Equivalent fractions with LCD
4/9=32/72
5/8=45/72
The denominators of each fractions are equal to each other.
Now, compare the numerators of fractions A and B. 45 is greater than 32
Therefore, 5/8 is greater than 4/9.
