Question

Поле площадью 18 га вспахали за 3 дня . В первый день вспахали 35% всего поля а ,во второй день 40% оставшейся площади .Сколько гектаров вспахали в 3 день.

Answer 1

18 * 0,35 = 6,3 (га)-вспахали в первый день

18 - 6,3 = 11,7 (га)-осталось невспаханной

11,7 * 0,4 = 4,68 (га)-вспахали во второй день

18 - 6,3 - 4,68 = 7,02 (га)-вспахали в третий день

Answer 2

Calculating the Area Plowed Each Day

To calculate the area plowed each day, we can use the information provided in the question and solve for the area plowed on the third day.

Given: - Total field area = 18 hectares - Plowing progress on the first day = 35% of the total field - Plowing progress on the second day = 40% of the remaining field

Let's calculate the area plowed on the third day step by step.

Step 1: Calculate the Area Plowed on the First Day

35% of 18 hectares = 0.35 * 18 = 6.3 hectares

Step 2: Calculate the Remaining Area After the First Day

18 hectares - 6.3 hectares = 11.7 hectares

Step 3: Calculate the Area Plowed on the Second Day

40% of 11.7 hectares = 0.40 * 11.7 = 4.68 hectares

Step 4: Calculate the Remaining Area After the Second Day

11.7 hectares - 4.68 hectares = 7.02 hectares

Step 5: Calculate the Area Plowed on the Third Day

The area plowed on the third day is the remaining area after the second day, which is 7.02 hectares.

The area plowed on the third day is 7.02 hectares.
