Math worksheet for converting time measurements and completing a multiplication table.

Let’s solve each part step by step.

Part 1: Reading Clocks (Problems 386–388)

We are given three clocks. We need to read the time shown on each.

- Clock 386:
The hour hand is between 1 and 2 → so it’s 1 o’clock something.
The minute hand is pointing at 9 → that’s 45 minutes (since each number = 5 minutes: 9 × 5 = 45).
So time is 1:45.

- Clock 387:
Already filled in as 4:28 — we don’t need to change this.

- Clock 388:
Already filled in as 1:54 — we don’t need to change this.

So for problem 386, the answer is 1:45.

Part 2: Convert Time Units (Problems 389–402)

We use these conversions:
- 1 hour = 60 minutes
- 1 minute = 60 seconds

Let’s go one by one:

389. 4 hr = ? min
→ 4 × 60 = 240 min

390. 60 min = ? hr
→ 60 ÷ 60 = 1 hr

391. 4 min = ? sec
→ 4 × 60 = 240 sec

392. 8 hr = ? min
→ 8 × 60 = 480 min

393. 9 min = ? sec
→ 9 × 60 = 540 sec

394. 6 min = ? sec
→ 6 × 60 = 360 sec

395. 3 hr = ? min
→ 3 × 60 = 180 min

396. 7 min = ? sec
→ 7 × 60 = 420 sec

397. 7 hr = ? min
→ 7 × 60 = 420 min

398. 9 hr = ? min
→ 9 × 60 = 540 min

399. 5 min = ? sec
→ 5 × 60 = 300 sec

400. 6 hr = ? min
→ 6 × 60 = 360 min

401. 10 hr = ? min
→ 10 × 60 = 600 min

402. 5 hr = ? min
→ 5 × 60 = 300 min

Part 3: Complete the Multiplication Table (Problem 403)

This is a multiplication table. The top row has numbers: 3, 4, 11, 10, 14, 19, 5, 16, 17, 13
The left column has numbers: 6, 13, 20, 19, 10

We multiply each row number by each column number.

Let’s build the table:

Row 1: Multiply 6 by each top number
6×3=18, 6×4=24, 6×11=66, 6×10=60, 6×14=84, 6×19=114, 6×5=30, 6×16=96, 6×17=102, 6×13=78

Row 2: Multiply 13 by each top number
13×3=39, 13×4=52, 13×11=143, 13×10=130, 13×14=182, 13×19=247, 13×5=65, 13×16=208, 13×17=221, 13×13=169

Row 3: Multiply 20 by each top number
20×3=60, 20×4=80, 20×11=220, 20×10=200, 20×14=280, 20×19=380, 20×5=100, 20×16=320, 20×17=340, 20×13=260

Row 4: Multiply 19 by each top number
19×3=57, 19×4=76, 19×11=209, 19×10=190, 19×14=266, 19×19=361, 19×5=95, 19×16=304, 19×17=323, 19×13=247

Row 5: Multiply 10 by each top number
10×3=30, 10×4=40, 10×11=110, 10×10=100, 10×14=140, 10×19=190, 10×5=50, 10×16=160, 10×17=170, 10×13=130

Now let’s write them in order.
