Question

за день Петя выкопал 12 ведер картофелях вместо намеченных 15. сколько процентов плана осталось невыполненно?

Answer 1

15 вёдер - 100 %

12 вёдер -  ? %

1) 12 х 100 : 15 = 80 % выполнил

2) 100 % - 80 % = 20 % осталось невыполненым.

Answer 2

1) Составим пропорцию:

15         -       100%

12        -          х

Перемножаем крест накрест:

1200=15х

х=80 %

2) 100-80=20%

Ответ: 20 %

Answer 3

Calculation of Percentage of Unfulfilled Plan

To calculate the percentage of the plan that remains unfulfilled, we can use the following formula:

Percentage unfulfilled = ((Planned - Actual) / Planned) * 100

Given that Peter dug up 12 buckets of potatoes instead of the planned 15, we can calculate the percentage of the plan that remains unfulfilled.

Using the formula: Percentage unfulfilled = ((15 - 12) / 15) * 100

Percentage unfulfilled = (3 / 15) * 100

Percentage unfulfilled = 20%

Therefore, Peter has only completed 80% of the planned work, and 20% of the plan remains unfulfilled.
