Let’s start with comparing… When you compare whole numbers, line up the digits and compare from left to right! 12,034,922 ____ 21,411,891 1 2,034,922 2 1,41 1,891 The 2 is bigger than 1, so 12,034,922 < 21,411,891

When you compare whole numbers, line up the digits and compare from left to right!

12,034,922 ____ 21,411,891

1 2,034,922

2 1,41 1,891

The 2 is bigger than 1, so

12,034,922 < 21,411,891
