Decimals and Place Value — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Use >, <, or = : 0.6 = 0.60.
0.6 = 0.60 — trailing zeros after a decimal digit don't change the value.
2. Use >, <, or = : 0.35 < 0.4.
0.35 = 35 hundredths; 0.4 = 40 hundredths. 35 < 40, so 0.35 < 0.4.
3. Order from least to greatest: 0.9, 0.09, 0.19. Answer: 0.09, 0.19, 0.9.
0.09 < 0.19 < 0.90 — comparing hundredths: 9 < 19 < 90.
4. The decimal 0.70 written in simplest fraction form is 710.
0.70 = 70100. Simplify by dividing by 10: 70100 = 710.
5. Use >, <, or = : 1.5 = 1.50.
1.5 = 1.50 — trailing zero doesn't change the value.
6. The decimal 0.03 is closest to 0 on a number line.
0.03 is 3 hundredths, very close to 0 on a number line.
7. Use >, <, or = : 0.8 > 0.78.
0.8 = 0.80 = 80 hundredths; 0.78 = 78 hundredths. 80 > 78, so 0.8 > 0.78.
8. In the number 9.14, the value of the digit 1 is 0.1.
In 9.14, the digit 1 is in the tenths place, with a value of 0.1.
9. Order from greatest to least: 0.5, 0.55, 0.05. Answer: 0.55, 0.5, 0.05.
0.55 > 0.50 > 0.05 — comparing: 55 > 50 > 5 hundredths.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
0.25
→ one quarter
halfway between 0 and 1
0.90
→ close to 1
close to 1
0.08
→ close to 0
one quarter
0.50
→ halfway between 0 and 1
close to 0
0.25=one quarter; 0.90=close to 1; 0.08=close to 0; 0.50=halfway between 0 and 1.
