Order from least to greatest 23,710; 23,751; 456,715

Your numbers are already in that order.

The number with the largest digit in the left-most corresponding number place is the largest number. If the left-most digits match, compare digits to the right of those. Repeat until you have determined the order or that the numbers are equal.

The number 456,715 is the largest, because it has 4 in the hundred-thousands place, where the other numbers have 0. The numbers 23710 and 23751 are the same in the ten-thousands, thousands, and hundreds place, so you need to compare the digits in the tens place. 5 is greater than 1, so 23751 is greater than 23710. Now that you know which numbers are greater, you can put them in the order you want.
