Question

Мастер выполнил 3/7 часть всего заказа. Первый ученик 5/14 часть, а второй ученик 1/14 часть. Был ли выполнен весь заказ? ​

Answer 1

Ответ:

3/7+5/14+1/14=6/14+6/14=12/14=6/7,

что не равняется 1, а значит 1/7 заказа еще не выполнена

Answer 2

Problem Analysis

We are given the information that a master has completed 3/7 of the total order, the first student has completed 5/14 of the order, and the second student has completed 1/14 of the order. We need to determine if the entire order has been completed.

Solution

To determine if the entire order has been completed, we need to calculate the total progress made by the master and the two students and compare it to the total order.

Let's calculate the progress made by each individual:

- The master has completed 3/7 of the order. - The first student has completed 5/14 of the order. - The second student has completed 1/14 of the order.

To find the total progress, we need to add up the progress made by each individual:

Total progress = Master's progress + First student's progress + Second student's progress

Total progress = 3/7 + 5/14 + 1/14

To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 14.

Total progress = (6/14) + (5/14) + (1/14)

Total progress = 12/14 + 5/14 + 1/14

Total progress = 18/14

Simplifying the fraction, we get:

Total progress = 9/7

Answer

The total progress made by the master and the two students is 9/7. Since the progress exceeds the total order, it means that the entire order has been completed.

Therefore, the entire order has been completed.
