Let's solve each problem step by step.
---
Problem 1:
52 hours × 3 = ______ hours
- Multiply the number of hours by 3:
\[
52 \times 3 = 156
\]
Answer:
\[
\boxed{156}
\]
---
Problem 2:
8 minutes × 22 = ______ minutes
- Multiply the number of minutes by 22:
\[
8 \times 22 = 176
\]
Answer:
\[
\boxed{176}
\]
---
Problem 3:
23 seconds × 7 = ______ seconds
- Multiply the number of seconds by 7:
\[
23 \times 7 = 161
\]
Answer:
\[
\boxed{161}
\]
---
Problem 4:
5 minutes 22 seconds + q minutes - r seconds = ______ minutes ______ seconds
- This problem is incomplete because it mentions variables \( q \) and \( r \) without providing their values. Without specific values for \( q \) and \( r \), we cannot compute the exact result. If you have additional information, please provide it.
---
Problem 5:
15 hours 9 minutes ÷ 4 = ______ hours ______ minutes
- First, convert the total time into a single unit (minutes):
\[
15 \text{ hours} = 15 \times 60 = 900 \text{ minutes}
\]
\[
900 \text{ minutes} + 9 \text{ minutes} = 909 \text{ minutes}
\]
- Divide the total minutes by 4:
\[
909 \div 4 = 227 \text{ R } 1
\]
This means 227 full minutes and a remainder of 1 minute.
- Convert 227 minutes back into hours and minutes:
\[
227 \text{ minutes} = 3 \text{ hours } 47 \text{ minutes}
\]
- Add the remainder (1 minute):
\[
3 \text{ hours } 47 \text{ minutes} + 1 \text{ minute} = 3 \text{ hours } 48 \text{ minutes}
\]
Answer:
\[
\boxed{3 \text{ hours } 48 \text{ minutes}}
\]
---
Problem 6:
2 hours × 6 = ______ hours
- Multiply the number of hours by 6:
\[
2 \times 6 = 12
\]
Answer:
\[
\boxed{12}
\]
---
Problem 7:
6 × 23 minutes = ______ minutes
- Multiply the number of minutes by 6:
\[
6 \times 23 = 138
\]
Answer:
\[
\boxed{138}
\]
---
Problem 8:
28 seconds × 5 = ______ seconds
- Multiply the number of seconds by 5:
\[
28 \times 5 = 140
\]
Answer:
\[
\boxed{140}
\]
---
Problem 9:
18 minutes 23 seconds × 2 = ______ minutes ______ seconds
- First, multiply the minutes by 2:
\[
18 \times 2 = 36 \text{ minutes}
\]
- Next, multiply the seconds by 2:
\[
23 \times 2 = 46 \text{ seconds}
\]
- Combine the results:
\[
36 \text{ minutes } 46 \text{ seconds}
\]
Answer:
\[
\boxed{36 \text{ minutes } 46 \text{ seconds}}
\]
---
Problem 10:
5 × 15 hours 13 minutes = ______ hours ______ minutes
- First, multiply the hours by 5:
\[
15 \times 5 = 75 \text{ hours}
\]
- Next, multiply the minutes by 5:
\[
13 \times 5 = 65 \text{ minutes}
\]
- Since 65 minutes is more than 60, convert the excess minutes into hours:
\[
65 \text{ minutes} = 1 \text{ hour } 5 \text{ minutes}
\]
- Add the extra hour to the total hours:
\[
75 \text{ hours} + 1 \text{ hour} = 76 \text{ hours}
\]
- The remaining minutes are 5.
Answer:
\[
\boxed{76 \text{ hours } 5 \text{ minutes}}
\]
