Given the decimal (approximate) representation of the number 0.54, it's required to find the equivalent fraction of the number.
If we use the exact number 0.54 and find its equivalent fraction, we notice none of the choices matches our result, so we assume 0.54 is an approximate representation of the real decimal number.
The best way to proceed now is to try each option:
A) 6/12 = 0.5
B) 6/11 = 0.5454...
C) 6/10 = 0.6
D) 6/9 = 0.66...
The best possible choice is B)
