Question

1 кг металобрухту замінює 2 1/2(2,5) кг залізної руди. студенти зібрали 4 тонни металобрухту. скільки руди зберегли студенти?​

Answer 1

4 000 · 2,5 = 10 000 (кг)

10 000 кг в тоннах делает - 10 тонн.

Answer 2

Ответ:

Пошаговое объяснение:

4т=4000кг

4000×2,5=10000кг=10т металобрухту зберегли

Answer 3

Calculation of Iron Ore Saved by Students

To calculate the amount of iron ore saved by the students, we need to determine the amount of iron ore required to produce 4 tons of scrap metal and compare it to the amount of iron ore saved.

According to the given information, 1 kg of scrap metal is equivalent to 2 1/2 (2.5) kg of iron ore.

Let's calculate the amount of iron ore required to produce 4 tons (4000 kg) of scrap metal:

1 kg of scrap metal = 2 1/2 (2.5) kg of iron ore 4000 kg of scrap metal = 4000 * (2 1/2) kg of iron ore

To calculate this, we can use the following formula:

Amount of iron ore saved = 4000 * (2 1/2) kg

Calculating this, we get:

Amount of iron ore saved = 4000 * 2.5 kg Amount of iron ore saved = 10000 kg

Therefore, the students have saved 10,000 kg of iron ore.

Note: The calculation assumes that the conversion rate between scrap metal and iron ore remains constant.
