What is the decimal expansion of the following fraction? a. 1.22 b. 0.22 c. 0.045 repeating over the 4 and 5 d. 0.045 repeating just over the 5

You haven't shared a fraction.  Please do that next time.

I checked and have found that 0.045 repeating over the 4 and 5 is equivalent to 1/22.  Try dividing 1 by 22 to verify this.

So I infer that the fraction you haven't yet shared is 1/22.

With a continuous thought process.
