- 0.45 has the largest number in the hundredths place and therefore the greatest value.
Problems 1.4 (page 5)
- 0.25 has the higher value. The decimal fraction that has the largest number representing the tenths
place has the higher value. 2 is higher than 1; therefore, 0.25 has a higher value than 0.125.
Problems 1.5 (page 6)
1. 0.24 0.5 0.125
Rewrite each number with the same number of decimal places:
0.24 equals 0.240 0.5 equals 0.500
Compare the numbers from left to right:
0.240, 0.500, 0.125 all have the same whole number.
- 0.500 or 0.5 has the largest number in the tenths place and therefore the greatest value.
