Give the following numbers to two decimal places: 123.7111, 3.4667, 7.61, 9.665, 10, and 53.499.
123.7111 becomes 123.71, because the first digit dropped is 1.
3.4667 becomes 3.47, because the first digit dropped is 6.
7.61 becomes 7.61, because it is already given to two decimal places
9.665 becomes 9.67, because the first digit dropped is 5.
10 becomes 10.00, because we need to add two empty decimal places.
53.499 becomes 53.50, because the first digit dropped is 9.
This raises the next digit from 9 to 10.
It becomes zero and the 4 before it becomes 5.
