Answer:
7700
Step-by-step explanation:
Note that 7 is in the thousandths place, 6 in the hundredths place, 8 in the tens place, and 4 in the ones place. Look at the 6. The number to the right of it is bigger than 5, which means that we bump the 6 to 7 and add 2 zeros on the end. (7684 becomes 7700)
