Multiplication and Money

We’ll do each multiplication or addition problem one at a time.

1. 65 × 10 = ?
Multiply 65 by 10 → just add a zero → 650

2. 86 × 100 = ?
Multiply 86 by 100 → add two zeros → 8,600

3. 78 × 1000 = ?
Multiply 78 by 1000 → add three zeros → 78,000

4. 174 × 10 = ?
Add a zero → 1,740

5. 950 × 100 = ?
Add two zeros → 95,000

Now the money additions:

6. $45.86 + $95.85
Line up decimals:
45.86
+ 95.85
--------
141.71 → $141.71

7. $456.95 + $847.79
456.95
+ 847.79
--------
1304.74 → $1,304.74

Now multiplications with money:

8. $36.26 × 65
Let’s break it down:
36.26 × 60 = 2175.60
36.26 × 5 = 181.30
Add them: 2175.60 + 181.30 = 2356.90 → $2,356.90

9. $99.75 × 36
Break it down:
99.75 × 30 = 2992.50
99.75 × 6 = 598.50
Add: 2992.50 + 598.50 = 3591.00 → $3,591.00

Now the division-style problems (find missing number):

10. 65 × 5 + ? = 408
65 × 5 = 325
408 - 325 = 83

11. 76 × 3 + ? = 282
76 × 3 = 228
282 - 228 = 54

12. 98 × 4 + ? = 460
98 × 4 = 392
460 - 392 = 68

13. 68 × 4 + ? = 510
68 × 4 = 272
510 - 272 = 238

14. 38 × 9 + ? = 441
38 × 9 = 342
441 - 342 = 99

Division – Identify the dividend

Remember: Dividend = divisor × quotient + remainder

15. 8 ) ___ = 28 r2
So: 8 × 28 + 2 = 224 + 2 = 226

16. 6 ) ___ = 36 r4
6 × 36 + 4 = 216 + 4 = 220

Now long division answers:

17. 6 ) 165
6 × 27 = 162 → remainder 3 → 27 r3

18. 8 ) 679
8 × 84 = 672 → remainder 7 → 84 r7

19. 5 ) 486
5 × 97 = 485 → remainder 1 → 97 r1

20. 7 ) 474
7 × 67 = 469 → remainder 5 → 67 r5

Money – Circle notes/coins to pay for items (least number possible)

We need to make each amount using fewest bills/coins. We assume standard Australian currency since images show AUD notes/coins.

Notes: $100, $50, $20, $10, $5
Coins: $2, $1, 50c, 20c, 10c, 5c

But since we can’t circle in text, we’ll list what you’d use.

- Tie: $12.80
Use: $10 note + $2 coin + 50c + 20c + 10c → total 5 pieces

- Shirt: $26.35
$20 + $5 + $1 + 20c + 10c + 5c → 6 pieces
OR better: $20 + $5 + $1 + 20c + 10c + 5c — same
Actually, maybe $20 + $5 + $1 + 20c + 10c + 5c is best.

Wait — let’s try to minimize:

$26.35 → $20 + $5 + $1 + 20c + 10c + 5c → 6 items
Can we do better? No, because no $2 coin used here? Wait, $2 coin exists.

Better: $20 + $5 + $1 + 20c + 10c + 5c — still 6.

Actually, if we use $2 coins:
$20 + $2 + $2 + $2 + $0.35 → but that’s more coins.

Stick with: $20 + $5 + $1 + 20c + 10c + 5c → 6 items

But wait — perhaps $20 + $5 + $1 + 20c + 10c + 5c is correct.

Actually, let's recalculate:

$26.35 = $20 + $5 + $1 + 20c + 10c + 5c → yes.

- Shoes: $45.60
$20 + $20 + $5 + 50c + 10c → 5 items
Or $20 + $20 + $5 + 50c + 10c — yes.

- Jacket: $67.90
$50 + $10 + $5 + $2 + 50c + 20c + 20c → too many
Better: $50 + $10 + $5 + $2 + 50c + 20c + 20c? Wait, 50+10+5+2=67, then 90c = 50c + 20c + 20c → 7 items

Alternative: $50 + $10 + $5 + $2 + 50c + 20c + 20c — same.

Or use $20s: $20×3 = $60, then $5 + $2 + 50c + 20c + 20c → also 7.

Actually, best: $50 + $10 + $5 + $2 + 50c + 20c + 20c — 7 items.

Wait — 90c can be 50c + 20c + 20c — yes.

But maybe 50c + 40c? But no 40c coin. So 50c + 20c + 20c is fine.

So for each item, we list minimal combination.

But since the question says “circle”, and we’re texting, we’ll just state the amounts are payable with those combinations.

Problem Solving

Jimmy bought:
- 2 kg salami @ $6.40/kg → 2 × 6.40 = $12.80
- 3 kg bananas @ $3.20/kg → 3 × 3.20 = $9.60

Total cost = 12.80 + 9.60 = $22.40

He paid with $50.00

Change = 50.00 - 22.40 = $27.60

- 38 × 9 + 99 = 441

Division:
- 8 ) 226 = 28 r2
- 6 ) 220 = 36 r4

Money (minimal coins/notes):
- Tie $12.80: $10 + $2 + 50c + 20c + 10c
- Shirt $26.35: $20 + $5 + $1 + 20c + 10c + 5c
- Shoes $45.60: $20 + $20 + $5 + 50c + 10c

Problem Solving:
Change from $50.00 after buying 2kg salami ($6.40/kg) and 3kg bananas ($3.20/kg) = $27.60

Final Answer:
$27.60
