Round off to the nearest 10-peso place value.
The number to the right of the ten-peso place value is 5. As a rule, when rounding off a number and the number to its right is 5 to 9, add 1 to the number.
When the number to the right of the number to be rounder off is 4 and below, the number remains.
NOTE: In real life involving rounding off money, always round up (add 1) so as not to be short of money. This is currently being taught in grade school, so that lessons in rounding off money is separated from rounding off plain integers.
