the numbers 15.254 and 14.546 should be rounded to which place value to be the same number after rounding

The ones places because 15.254 rounded to the ones place is 15 (since the tenths place is less than .5 so you round down) and also if you round 14.546 to the ones place you also get 15 (since the tenth place is .5 or more you round up)

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
