Answer: C. 4.647
Step-by-step explanation:
We round up numbers from 5-7 and we round down numbers from 1-4
In option A 4.746 can be rounded off to 4.7 because the number after 7 is 4, so the number is rounded down to 4.7
In option B 4.680 can be rounded off to 4.7 because the number after 6 is 8 therefore the number is rounded up to 4.7
In option D 4.733 can be rounded off to 4.7 because the number after 7 is 3, so 4.733 will be rounded down to 7.4
In option C, 4.647 can be rounded off to 4.6 because the number after 6 is 4 , so 4.647 will be rounded down to 4.6
Only option c is 4.6 therefore our answer is c.
