1) 3 + 0.4 =
Think of it as 3 whole things plus 4 tenths → that’s 3.4
→
Answer: 3.4
---
2) What is the value of the digit 4 in the number 825.4?
The 4 is after the decimal point — that’s the tenths place. So its value is 4 tenths, or 0.4

→
Answer: 6
---
5) 3.4 + 2.3 =
Add the whole numbers: 3 + 2 = 5
Add the decimals: 0.4 + 0.3 = 0.7
Total: 5 + 0.7 = 5.7
→
Answer: 5.7
---
6) 0.4 + ___ = 1
What do we add to 0.4 to get 1?
1 - 0.4 = 0.6
→
Answer: 0.6
---
7) 8.4 = 8 + ____
Break apart 8.4 → 8 wholes and 0.4 left over
→
Answer: 0.4
---
8) 12 + 0.4 =
Just combine them → 12.4
→
Answer: 12.4
---
9) 7.3 = _____ + 0.3

7.3 - 0.3 = 7.0
→
Answer: 7
---
10) 1 ÷ 10 = ________ (decimal) or ________ (fraction)
Dividing by 10 moves the decimal one place left → 0.1
As a fraction: 1/10
→
Answer: 0.1 (decimal), 1/10 (fraction)
---
11) Use >, <, or = : 8.4 ___ 8.2
Compare the tenths: 4 > 2 → so 8.4 is bigger
→
Answer: >
---
12) How many tenths make a whole?
One whole = 10 tenths (because 10 × 0.1 = 1)
→
Answer: 10
---
13) Which is bigger: 14 tenths or 2 ones?
14 tenths = 1.4
2 ones = 2.0
2.0 > 1.4 → so 2 ones is bigger
→
Answer: 2 ones
---
14) 1.3 = _______ tenths
1.3 = 1 whole + 0.3 = 10 tenths + 3 tenths = 13 tenths
→

Subtract: 3.7 - 3 = 0.7
→
Answer: 0.7
---

Look at the whole number part: 4 < 5 → so 4.6 < 5.3
→
Answer: <
---
18) 1 – 0.1 =
Take away 1 tenth from 1 whole → leaves 0.9
→
Answer: 0.9
---
19) How many tenths make 2 ones?
1 one = 10 tenths → 2 ones = 20 tenths
→
Answer: 20
---
