In order to know which numbers are less than , you can convert this fraction into a decimal number. To do this, you need to divide the numerator 9 by the denominator 4. Then:
Now you need convert the fractions provided in the Options A and B into decimal numbers by applying the same procedure. This are:
Option A→ (It is not less than 2.25)
Option B→ (It is less than 2.25)
The number shown in Option C is already expressed in decimal form:
Option C→ (It is less than 2.25)
