43 × 15 = 645.
First, set up the long multiplication.
Second, calculate 3 × 5, which is 15. Since 15 is two-digit, carry the first digit 1 to the next column.
Third, calculate 4 × 5 which is 20. Since 21 is two-digit, carry the first digit 2 to the next column.
Fourth, bring down the carry digit of 2.
Fifth, calculate 3 × 1, which is 3.
Sixth, calculate 4 × 1, which is 4.
Seventh, calculate 215 + 430, which is 645.
Eighth, therefore, 43 × 15 = 645.
Or.. an easier way is to use a calculator. They always come in handy when doing multiplication.

Step-by-step explanation:
What is 3/4 full mean in this question? It means that you take 3/4 of 60000 and that's how many liters are already in the pool. Your job is to fill the remainder using the rest of the information.
3/4 * 60000 = 45000
There are already 45000 liters in the pool.
You need to put in an addition 60000 - 45000 = 15000 liters
So how many 10 L buckets do you have to fill to get 15000?
15000 / 10 = 1500
You need to fill 1500 buckets to get the pool filled.
Since 1 bucket takes 1 minute, it will take 1500 minutes to fill the pool.
1500 minutes * 1 hour / 60 minutes = 25hours
Answer: 25 hours or 1 day and 1 hour
