I'll work through each problem step by step, converting the given amounts to decimal form.
Problem 1: Three tenths plus five hundredths of a dollar
- Three tenths = 0.3
- Five hundredths = 0.05
- Total: 0.3 + 0.05 =
$0.35
Problem 2: Seven tenths plus five hundredths of a dollar
- Seven tenths = 0.7
- Five hundredths = 0.05
- Total: 0.7 + 0.05 =
$0.75
Problem 3: Eight tenths plus one hundredth of a dollar
- Eight tenths = 0.8
- One hundredth = 0.01
- Total: 0.8 + 0.01 =
$0.81
Problem 4: Nine tenths of a dollar
- Nine tenths = 0.9
- Answer:
$0.90 (or $0.9)
Problem 5: Two tenths plus nine hundredths of a dollar
- Two tenths = 0.2
- Nine hundredths = 0.09
- Total: 0.2 + 0.09 =
$0.29
Problem 6: $\frac{5}{10} - \frac{3}{10}$ of a dollar
- $\frac{5}{10} = 0.5$
- $\frac{3}{10} = 0.3$
- Subtraction: 0.5 - 0.3 =
$0.20 (or $0.2)
Problem 7: $\frac{7}{10}$ of a dollar
- $\frac{7}{10} = 0.7$
- Answer:
$0.70 (or $0.7)
Problem 8: Two dollars plus $\frac{3}{10}$ of a dollar
- Two dollars = 2.00
- $\frac{3}{10} = 0.3$
- Total: 2.00 + 0.3 =
$2.30
Problem 9: Four dollars plus $\frac{7}{100}$ of a dollar
- Four dollars = 4.00
- $\frac{7}{100} = 0.07$
- Total: 4.00 + 0.07 =
$4.07
Problem 10: Five dollars plus six tenths of a dollar
- Five dollars = 5.00
- Six tenths = 0.6
- Total: 5.00 + 0.6 =
$5.60
Problem 11: Ten dollars plus $\frac{1}{10}$ of a dollar
- Ten dollars = 10.00
- $\frac{1}{10} = 0.1$
- Total: 10.00 + 0.1 =
$10.10
Problem 12: One dollar plus nine hundredths of a dollar
- One dollar = 1.00
- Nine hundredths = 0.09
- Total: 1.00 + 0.09 =
$1.09
