Tutor: Not quite. Have another look.
Objective: round numbers to the nearest hundred | incorrect - the student never got there and the tutor supplied the answer | null | Tutor: No, not half. "Round up" means we increase the hundreds digit by one. Since we're rounding to the nearest hundred, we look at the tens digit, which is 7. Because 7 is 5 or more, we round up. This means the 6 in the hundreds place becomes a 7, and the tens and ones digits become zeros. So, 4,672 becomes 4,700. |
