Step-by-step explanation:

The ratio's can be expressed as fractions and you may compare those.

  • 5 : 8 = 5/8
  • 7 : 9 = 7/9

In order to compare fractions you need to bring them into equal denominator.

8 and 9 have LCM of 8*9 = 72 since they have no common factors.

The equivalent fractions with common denominator are:

  • 5/8 = 9*5/(9*8) = 45/72
  • 7/9 = 8*7/(8*9) = 56/72

Now we can compare the fractions:

  • 45/72 < 56/72, since 45 < 56
