Comparing Decimal Amounts

 When comparing decimals, look at the largest places first. Compare using the

largest place that is different.

Compare using tenths place:

The digit in the tenths place is the same.

0.7 is greater than 0.4

Compare using hundredths:

0.7 > 0.4

0.43 is less than 0.48

0.43 < 0.48

Compare using tenths place:

Compare using tenths place: 0.7

0.7 is greater than 0.43

0.7 is the same as 0.70

0.7 > 0.43

0.7 = 0.70

(Remember that 0.7 = 0.70)
