Answer:
0.511
Explanation:
For this problem, there is no simplification to be had. You will simply need to use the numerator borrow method (assuming no calculator):
23 / 45 ~= 0
23.0 / 45 ~= 0.5 ( 5 * 45 = 225 )
23.00 / 45 ~= 0.51 ( 1 * 45 = 45 )
23.000 / 45 ~= 0.51 ( 1 * 45 = 45 )
.
.
.
Hence, we can say 23 / 45 is approximately 0.51 repeating.
Cheers.
