Let’s go through each problem one by one and solve them carefully.
---
1) 3 + 0.4 =
We’re adding a whole number and a decimal.
3 is the same as 3.0, so:
3.0 + 0.4 =
3.4
✔ Correct.
---
2) What is the value of the digit 4 in the number 825.4?
In 825.4, the 4 is in the tenths place (first digit after the decimal).
So its value is
0.4 or
four tenths.
✔ Correct.
---
3) 7 + 0.3 =
7 is 7.0 → 7.0 + 0.3 =
7.3
✔ Correct.
---
4) 0.6 = ______ tenths
0.6 means 6 tenths. So:
6
✔ Correct.
---
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
✔ Correct.
---
6) 0.4 + ___ = 1
What do we add to 0.4 to get 1?
1 - 0.4 =
0.6
✔ Correct.
---
7) 8.4 = 8 + ____
8.4 means 8 wholes and 4 tenths →
0.4
✔ Correct.
---
8) 12 + 0.4 =
12.0 + 0.4 =
12.4
✔ Correct.
---
9) 7.3 = _____ + 0.3
Subtract 0.3 from 7.3: 7.3 - 0.3 =
7
✔ Correct.
---
10) 1 ÷ 10 = ________ (decimal) or ________ (fraction)
1 divided by 10 is
0.1 as a decimal, and
1/10 as a fraction.
✔ Correct.
---
**11) Use the symbol >, < or =
8.4 ___ 8.2**
Compare: 8.4 is bigger than 8.2 →
>
✔ Correct.
---
12) How many tenths make a whole?
One whole = 10 tenths →
10
✔ Correct.
---
13) Which is bigger: 14 tenths or 2 ones?
14 tenths = 1.4
2 ones = 2.0
2.0 > 1.4 →
2 ones
✔ Correct.
---
14) 1.3 = _______ tenths
1.3 = 13 tenths →
13
✔ Correct.
---
15) What is the value of the digit 6 in the number 793.6?

0.6
✔ Correct.
---
16) 3 + _____ = 3.7
3.7 - 3 =

✔ Correct.
---
**17) Use the symbol >, < or =
4.6 ___ 5.3**
4.6 is less than 5.3 →
<
✔ Correct.
---
18) 1 – 0.1 =
1.0 - 0.1 =
0.9
✔ Correct.
---
19) How many tenths make 2 ones?
1 one = 10 tenths → 2 ones = 20 tenths →
20
✔ Correct.
---
20) 16 tenths =
16 tenths = 1.6 →
1.6
✔ Correct.
