When rounding the number 63 to the nearest ten, it becomes 60 because it is closer to 60 than to 70. If rounding to the nearest whole number, it remains 63 since it is already a whole number. Depending on the context, rounding can vary, but typically these are the standard practices.
60% of 63 = 0.60 * 63 = 37.8
Numbers such as this are rounded down if the end digit is 1 to 4 and rounded up if the end digit is 5 to 9. So, 55, 56, 57, 58 and 59 would be rounded up to 60. 60 is unchanged. 61, 62, 63 and 64 would be rounded down to 60. The number is therefore any number from 55 to 64 inclusive.
63 rounds to 60.
63/60 of 100 = 105%
