Answer 1

1/3+1/6=2/6+1/6=3/6=1/2(часть)-заказа выполнят за 1 день они вмести

Answer 2

Calculation of Work Efficiency

To determine the portion of the order that a seamstress and her apprentice can complete in one day while working together, we need to consider their individual work rates.

According to the information provided, the seamstress can complete the order in 3 days, while her apprentice can complete the same order in 6 days.

To calculate their combined work efficiency, we can use the concept of "work done per unit of time." Let's assume that the entire order is considered as one unit of work.

The seamstress can complete the order in 3 days, which means her work rate is 1/3 of the order per day. Similarly, the apprentice can complete the order in 6 days, so her work rate is 1/6 of the order per day.

To find the portion of the order they can complete together in one day, we need to add their individual work rates:

1/3 + 1/6 = 1/2

Therefore, when working together, the seamstress and her apprentice can complete 1/2 of the order in one day.

Please note that this calculation assumes that their work rates remain constant throughout the entire duration of the order.
