To find out how much greater the number 0.127 is compared to 1/8, we subtract 1/8 from 0.127.
0.127 - 1/8 = 0.127 - 0.125
To subtract these two numbers, we need to find a common denominator. The common denominator of 8 and 125 is 1000.
So, we have:
0.127 - 0.125 = 127/1000 - 125/1000
Now, we can subtract the numerators:
0.127 - 0.125 = (127 - 125)/1000
Simplifying the numerator:
0.127 - 0.125 = 2/1000
Simplifying the fraction:
0.127 - 0.125 = 1/500
Therefore, the number 0.127 is 1/500 greater than 1/8.
The correct answer is D) 1/500.
