Questions & Step-by-Step Solutions
A worker can complete a job in 10 days. How much work can he complete in 3 days?
Step 1: Understand that the worker can finish the entire job in 10 days.
Step 2: Calculate how much work the worker does in one day. This is done by taking 1 job and dividing it by 10 days, which gives us 1/10 of the job per day.
Step 3: Now, we want to find out how much work the worker can complete in 3 days.
Step 4: To find the work done in 3 days, multiply the work done in 1 day (1/10) by 3 days. This is 3 × (1/10).
Step 5: Calculate the result of 3 × (1/10), which equals 3/10. This means the worker can complete 3/10 of the job in 3 days.
Work Rate – Understanding how to calculate work done based on a worker's rate of completing a job.
Proportionality – Applying proportional reasoning to determine the amount of work completed over a specific time period.
