Answer

$3925 \approx 3930$ $11,243 \approx 11,240$ $15,974 \approx 15,970$ $17,916 \approx 17,920$ $534,883 \approx 534,880$ $2,788,000 \approx 2,788,000$

Work Step by Step

Round each number to the nearest 10. If the digit in the ones position is 4 or less, leave the number in the tens position as is and move zero to the ones position. If the digit in the ones position is 5 or greater, add one to the number in the tens position and move zero to the ones position. $3925 \approx 3930$ $11,243 \approx 11,240$ $15,974 \approx 15,970$ $17,916 \approx 17,920$ $534,883 \approx 534,880$ $2,788,000 \approx 2,788,000$
