Answer:
Option C: 4
Step-by-step explanation:
Given that:
= 9 / 2 1/4 --------- eq1
As 2 1/4 is mixed number it can be changed into the fraction by multiplying the denominator by the quotient and adding numerator into the answer.
So 2 1/4 = (4 *2 +1)/4 = 9/4
Putting in eq1 we get:
= 9/ 9/4
By inverting the lower fraction the division sign will be changed into multiplication.
= 9 * 4 / 9
Both 9's will be cancelled out:
= 4
