Answer:
D. 0.343
Step-by-step explanation:
You can see the first three options as 0.340 so if you substract this number with 0.343 the remainder is positive 3.
This strategy also can be applied to the number 0.3409 but in this occasion the result is different:
That is small number but still is positive that's meaning that between 0.343 and 0.3409 the greatest value is 0.343 .
