... add to 3 so the remaining digits need to add to at least 13. The right most digit varies from 0 to 9 while the digit to its right will display the digits from 0 to 5. In order to have a sum of at least 13, we could have 49, 59, or 58. At the 11 o’clock hour, the first two digits add to 2, so we need ...

... unit to another. For example: a medium-sized bug is 8.4 mm in length. Express this length in meters. First, consider if the number should be bigger or smaller than 8.4. Which is the bigger unit? The meter is the bigger unit so the answer should be smaller than 8.4. The equivalences are used as ratio ...
