Expressed as a ratio it is 22 : 18This can be simplified as both numbers are divisible by 2 to become, 11 : 9Ratios can be shown as fractions :22/18 or 11/9They can also be shown as percentages provided the basenumber is clearly identified.If 22 is the base number then 18 is 18/22 x 100 = 81.82% of 22. (2dp)If 18 is the base number then 22 is 22/18 x 100 = 122.22% of 18. (2dp)
