Comparing Numbers

100

7 hundredths O .7

7 hundredths < .7

200

821 hundredths + 2 tenths O 7 + 1.13

821 hundredths + 2 tenths > 7 + 1.13

or

8.41 > 8.13

300

12 + 72 x10³ O 84 x 10²

12 + 72 x10^{3 >} 84 x 10²

or 

84000 > 8400

400

7.2 ÷ 10 O 72 ÷ 10²

7.2 ÷ 10 = 72 ÷ 10²

or

.72 = .72

500

.4 x 10² + .0008 x 10⁴ O .4 x 10 + .8 x 10³

.4 x 10² + .0008 x 10⁴ < .4 x 10 + .8 x 10³

or

48<804
