On the place value chart, label the units and represent the number 50,679

The 5 is under the ten thousand column, so it represents 50,000. The 0 is under the thousands column, but doesn't represent anything since it's 0. The 6 is under the hundreds column and so it represents 600. The 7 is under the tens column and so it is 70, while the 9 is in the units or the ones (What you call it) and so it is 9

1.3 and 1 1/3 are both closest to 1. hope this ; )
