Answer:
(b) 5 2/5
Explanation:
You can figure this one by estimating. The denominator on the right is a little more than double the numerator. Then the denominator on the left (x) will be a little more than double the numerator. Double is 2(2 1/4) = 4 1/2.
The closest reasonable value is 5 2/5.

If you want to work this out in detail, you will see that ...
x = (2 1/4(3 3/5)/(1 1/2)
x = (9/4)(18/5)(2/3) = (9·18·2)/(4·5·3) = 3·18/10 = 5.4 = 5 2/5
