Questions & Step-by-Step Solutions
If a man can complete a work in 15 days, how much work can he complete in 5 days?
Step 1: Understand that the man can complete the entire work in 15 days.
Step 2: Determine how much work he can do in one day by dividing the total work (1 whole work) by the number of days (15). This gives us 1/15 of the work per day.
Step 3: Calculate how much work he can complete in 5 days by multiplying the work done in one day (1/15) by the number of days (5). This is 5 * (1/15).
Step 4: Simplify the calculation: 5/15 equals 1/3.
Step 5: Conclude that the man can complete 1/3 of the work in 5 days.
