Decimals and Place Value — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which is greater: 0.3 or 0.25?
A) 0.25 because it has more digits
B) 0.3 because 30 hundredths > 25 hundredths
C) They are equal
D) 0.25 because 25 > 3
0.3 = 30100 and 0.25 = 25100. Since 30 > 25, 0.3 > 0.25.
2. What is the expanded form of 0.62?
A) 6 ones + 2 tenths
B) 6 tenths + 2 hundredths
C) 62 tenths
D) 6 hundredths + 2 thousandths
0.62 = 0.6 + 0.02 = 6 tenths + 2 hundredths.
3. What is 410 + 35100 as a decimal?
A) 0.39
B) 0.435
C) 0.75
D) 4.35
410 = 40100; 40100 + 35100 = 75100 = 0.75.
4. Which list is ordered from least to greatest?
A) 2.9, 2.19, 2.1, 2.09
B) 2.1, 2.09, 2.19, 2.9
C) 2.09, 2.1, 2.19, 2.9
D) 2.09, 2.19, 2.1, 2.9
Converting to hundredths: 2.09 < 2.10 < 2.19 < 2.90 — ordered from least to greatest.
Part B: Fill in the Blank
Write the correct answer on each line.
1. The decimal 0.04 equals the fraction 4 100 .
0.04 = 4 hundredths = 4100.
2. 3 tenths + 17 hundredths = 47 hundredths total.
3 tenths = 30 hundredths; 30 + 17 = 47 hundredths.
3. The number 0.8 written in hundredths is 0.80.
0.8 = 0.80 — adding a zero in the hundredths place doesn't change the value.
4. Place the correct symbol (>, <, =): 0.41 > 0.14.
0.41 = 41 hundredths; 0.14 = 14 hundredths. 41 > 14, so 0.41 > 0.14.
5. A pencil costs $0.89. That is 89 hundredths of a dollar.
$0.89 = 89 hundredths of a dollar = 89 cents.
