Let’s go through each problem one by one. The goal is to write each value as a decimal number (like $0.32 or $5.90). We’ll use what we know about money and decimals:
- 1 tenth of a dollar = $0.10
- 1 hundredth of a dollar = $0.01
- So, “three tenths” = 3 × $0.10 = $0.30
- “two hundredths” = 2 × $0.01 = $0.02
- Add them: $0.30 + $0.02 = $0.32 → which matches the example given!
Now let’s solve each:
---
1. Three tenths plus two hundredths of a dollar
→ 3 × 0.10 = 0.30
→ 2 × 0.01 = 0.02
→ 0.30 + 0.02 =
0.32
---
2. Seven tenths plus five hundredths of a dollar
→ 7 × 0.10 = 0.70
→ 5 × 0.01 = 0.05
→ 0.70 + 0.05 =
0.75
---
3. Eight tenths plus one hundredth of a dollar
→ 8 × 0.10 = 0.80
→ 1 × 0.01 = 0.01
→ 0.80 + 0.01 =
0.81
---
4. Nine tenths of a dollar
→ 9 × 0.10 =
0.90
---
5. Two tenths plus nine hundredths of a dollar
→ 2 × 0.10 = 0.20
→ 9 × 0.01 = 0.09
→ 0.20 + 0.09 =
0.29
---
6. 6/10 + 3/100 of a dollar
→ 6/10 = 0.60
→ 3/100 = 0.03
→ 0.60 + 0.03 =
0.63
---
7. 7/10 of a dollar
→ 7 ÷ 10 =
0.70
---
8. Two dollars plus 4/10 of a dollar
→ 2 dollars = 2.00
→ 4/10 = 0.40
→ 2.00 + 0.40 =
2.40
---
9. Four dollars plus 1/100 of a dollar
→ 4 dollars = 4.00
→ 1/100 = 0.01
→ 4.00 + 0.01 =
4.01
---
10. Five dollars plus six tenths of a dollar
→ 5 dollars = 5.00
→ 6/10 = 0.60
→ 5.00 + 0.60 =
5.60
---
11. Ten dollars plus 1/10 of a dollar
→ 10 dollars = 10.00
→ 1/10 = 0.10
→ 10.00 + 0.10 =
10.10
---
12. One dollar plus nine hundredths of a dollar
→ 1 dollar = 1.00
→ 9/100 = 0.09
→ 1.00 + 0.09 =
1.09
---
