When rounding a number to the nearest ten, you look at the digit in the ones place. If the ones digit is 5 or greater, you round up; if it is less than 5, you round down. In this case, 50 has a zero in the ones place, so it remains the same when rounded to the nearest ten. Therefore, 50 rounded to the nearest ten is still 50.
