Answer:
No, Sorry.
Step-by-step explanation:
Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.
Example) 1/2 - 3/4

Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.

The subtract from there.

and then Reduce (if needed.)

You do 27x27 and get 729 is going to be your answer
45 divided by 50= 90%
0.9*16.50=14.85
