Let’s solve each problem one by one, step by step.
---
Problem 1:
Kyle brushes his teeth
3 times a day.
He does this for
7 days in a row.
To find total brushings: multiply 3 × 7 =
21
✔ Check: 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 → Correct.

Problem 2:
Shana lost:
- 2 teeth at age six
- 3 teeth at age seven
- 3 teeth at age eight
- 4 teeth at age nine
Add them up: 2 + 3 = 5; 5 + 3 = 8; 8 + 4 =
12
✔ Check: 2+3+3+4 = 12 → Correct.
---
Problem 3:
Dad bought
4 packs of dental floss.
Each pack holds
1 yard.
So total yards = 4 × 1 =
4 yards
But we need
feet.
1 yard = 3 feet → So 4 yards = 4 × 3 =
12 feet
✔ Check: 4 packs × 3 feet per pack = 12 feet → Correct.

Problem 4:
Sue, Bob, Ray, and Paul → that’s
4 people.
Each goes to the dentist
2 times a year.
Total visits = 4 × 2 =
8
✔ Check: 2 + 2 + 2 + 2 = 8 → Correct.

Problem 5:
Betty drinks
4 glasses of milk each day.
For
6 days, total glasses = 4 × 6 =
24
✔ Check: 4 + 4 + 4 + 4 + 4 + 4 = 24 → Correct.

Final Answer:
1. 21
2. 12
3. 12
4. 8
5. 24
