Question: If a man can do a piece of work in 15 days, how much work can he do in 3 days?

Solution:

In 1 day, he does 1/15 of the work. In 3 days, he does 3/15 = 1/5 of the work.

If a man can do a piece of work in 15 days, how much work can he do in 3 days?

If a man can do a piece of work in 15 days, how much work can he do in 3 days?

Step 1: Understand that the man can complete the entire work in 15 days.
Step 2: Calculate how much work he does in 1 day. This is done by taking the total work (1 whole) and dividing it by the number of days (15). So, in 1 day, he does 1/15 of the work.
Step 3: Now, to find out how much work he can do in 3 days, multiply the amount of work he does in 1 day (1/15) by 3. This gives us 3/15.
Step 4: Simplify 3/15. This can be simplified to 1/5 by dividing both the numerator and the denominator by 3.
