Question

Латунь состоит из 2 частей цинка и 3 частей меди. Сколько грамм меди в куске латуни массой 450 грамм ?

Answer 1

Если нужно с иксом - тогда
х - это одна часть
2х - часть цинка
3х - часть меди
2х+3х=450
5х=450
х=90 - одна часть
2х=180 г цинка
3х=270 г меди

Answer 2

Calculating the Amount of Copper in a 450-Gram Brass Ingot

To calculate the amount of copper in a 450-gram brass ingot, we can use the given ratio of zinc to copper in brass, which is 2 parts zinc to 3 parts copper.

Step 1: Calculate the total parts of the brass ingot: - The total parts of the brass ingot are 2 (zinc) + 3 (copper) = 5 parts.

Step 2: Calculate the amount of copper in the 450-gram brass ingot: - To find the amount of copper in the 450-gram brass ingot, we can use the following formula: - Amount of copper = (3 parts / 5 parts) * 450 grams - Amount of copper = (3/5) * 450 - Amount of copper = 270 grams

Conclusion: The 450-gram brass ingot contains 270 grams of copper.

This calculation is based on the given ratio of zinc to copper in brass and the total mass of the brass ingot.
