Let’s solve each problem step by step. We’re multiplying money amounts (dollars and cents) by whole numbers. Remember: treat the dollar amount like a decimal number, multiply normally, then put the dollar sign back on the answer.
We’ll go one by one:
---
1. $10.00 × 2
10.00 × 2 = 20.00 →
$20.00
2. $23.11 × 5
23.11 × 5:
23 × 5 = 115
0.11 × 5 = 0.55
Total = 115 + 0.55 = 115.55 →
$115.55
3. $9.78 × 3
9.78 × 3:
9 × 3 = 27
0.78 × 3 = 2.34
Total = 27 + 2.34 = 29.34 →
$29.34
4. $45.07 × 6
45.07 × 6:
45 × 6 = 270
0.07 × 6 = 0.42
Total = 270 + 0.42 = 270.42 →
$270.42
5. $55.10 × 7
55.10 × 7:
55 × 7 = 385
0.10 × 7 = 0.70
Total = 385 + 0.70 = 385.70 →
$385.70
6. $5.45 × 4
5.45 × 4:
5 × 4 = 20
0.45 × 4 = 1.80
Total = 20 + 1.80 = 21.80 →
$21.80
7. $7.20 × 8
7.20 × 8:
7 × 8 = 56
0.20 × 8 = 1.60
Total = 56 + 1.60 = 57.60 →
$57.60
8. $16.33 × 5
16.33 × 5:
16 × 5 = 80
0.33 × 5 = 1.65
Total = 80 + 1.65 = 81.65 →
$81.65
9. $68.24 × 2
68.24 × 2:
68 × 2 = 136
0.24 × 2 = 0.48
Total = 136 + 0.48 = 136.48 →
$136.48
10. $70.07 × 7
70.07 × 7:
70 × 7 = 490
0.07 × 7 = 0.49
Total = 490 + 0.49 = 490.49 →
$490.49
11. $11.56 × 3
11.56 × 3:
11 × 3 = 33
0.56 × 3 = 1.68
Total = 33 + 1.68 = 34.68 →
$34.68
12. $10.00 × 9
10.00 × 9 = 90.00 →
$90.00
13. $15.00 × 2
15.00 × 2 = 30.00 →
$30.00
14. $31.72 × 4
31.72 × 4:
31 × 4 = 124
0.72 × 4 = 2.88
Total = 124 + 2.88 = 126.88 →
$126.88
15. $6.15 × 5
6.15 × 5:
6 × 5 = 30
0.15 × 5 = 0.75
Total = 30 + 0.75 = 30.75 →
$30.75
