Let’s solve this step by step.
We are converting units of measure:
- Centimeters (cm) to millimeters (mm): multiply by 10 → because 1 cm = 10 mm
- Millimeters (mm) to centimeters (cm): divide by 10 → because 10 mm = 1 cm
- Dollars ($) to cents: multiply by 100 → because $1 = 100 cents
- Cents to dollars ($): divide by 100 → because 100 cents = $1

120 mm
63 cm → 63 × 10 =
630 mm
92 cm → 92 × 10 =
920 mm
15 cm → 15 × 10 =
150 mm
38 cm → 38 × 10 =
380 mm
98 cm → 98 × 10 =
980 mm
20 cm → 20 × 10 =
200 mm
9 cm → 9 × 10 =
90 mm
42 cm → 42 × 10 =
420 mm
105 cm → 105 × 10 =
1050 mm
426 cm → 426 × 10 =
4260 mm
✔ All correct.

Part 2: Convert these millimeters to centimeters
Divide each number by 10.
35 mm → 35 ÷ 10 =
3.5 cm
65 mm → 65 ÷ 10 =
6.5 cm
130 mm → 130 ÷ 10 =
13 cm
320 mm → 320 ÷ 10 =
32 cm
90 mm → 90 ÷ 10 =
9 cm
32 mm → 32 ÷ 10 =
3.2 cm
120 mm → 120 ÷ 10 =
12 cm
200 mm → 200 ÷ 10 =
20 cm
460 mm → 460 ÷ 10 =
46 cm
✔ All correct.

Part 3: Convert these dollars to cents
Multiply each dollar amount by 100.
$35 → 35 × 100 =
3500 cents
$11 → 11 × 100 =
1100 cents
$72 → 72 × 100 =
7200 cents
$602 → 602 × 100 =
60200 cents
$30 → 30 × 100 =
3000 cents
$4 → 4 × 100 =
400 cents
$15 → 15 × 100 =
1500 cents
$95 → 95 × 100 =
9500 cents
$250 → 250 × 100 =
25000 cents
✔ All correct.

Part 4: Convert these cents to dollars
Divide each cent amount by 100.
450¢ → 450 ÷ 100 =
$4.50
250¢ → 250 ÷ 100 =
$2.50
1071¢ → 1071 ÷ 100 =
$10.71
900¢ → 900 ÷ 100 =
$9.00
400¢ → 400 ÷ 100 =
$4.00
6000¢ → 6000 ÷ 100 =
$60.00
150¢ → 150 ÷ 100 =
$1.50
395¢ → 395 ÷ 100 =
$3.95
25000¢ → 25000 ÷ 100 =
$250.00
✔ All correct.
