2)3* 4/15 =4/5(работы)-будет выполнено при совместной работе

                                     обоих слесарей за 3 часа

3)1- 4/5=5/5-4/5=1/5(работы)-останется невыполненной после 3-х часов совместной 

                                               работы

Answer 2

Calculation of the Unfinished Portion of the Order

To calculate the unfinished portion of the order after three hours of joint work by both locksmiths, we need to determine the amount of work each locksmith can complete in one hour.

Let's assume that the first locksmith can complete the entire order in 6 hours, which means they can complete 1/6th of the order in one hour. Similarly, the second locksmith can complete the entire order in 10 hours, so they can complete 1/10th of the order in one hour.

Now, let's calculate the combined work done by both locksmiths in three hours:

- The first locksmith can complete 1/6th of the order in one hour, so in three hours, they can complete 3 * (1/6) = 1/2 of the order. - The second locksmith can complete 1/10th of the order in one hour, so in three hours, they can complete 3 * (1/10) = 3/10 of the order.

To find the unfinished portion of the order, we subtract the combined work done by both locksmiths from the total order:

- Total order = 1 - Combined work done by both locksmiths = 1/2 + 3/10 = 5/10 + 3/10 = 8/10

Therefore, the unfinished portion of the order after three hours of joint work by both locksmiths is:

1 - 8/10 = 2/10 = 1/5

So, one-fifth of the order will remain unfinished after three hours of joint work by both locksmiths.
