Question

Когда израсходовали 78 целых 2/5 кг картофеля,то оказалось что израсходовано 49/200 всего запаса.Сколько килограммов картофеля было запасено?Помгите прошуу

Answer 1

78 2/5 кг = 78400 грамм и составляет 49/200 от всего картофеля, значит 78400:49•200 = 320000 грамм или 320 кг было запасено

Answer 2

Solution:

To solve this problem, we can use a proportion to find the total amount of potatoes that were originally in stock.

Let's denote the total amount of potatoes originally in stock as x kilograms.

We know that when 78 2/5 kilograms were used, it represented 49/200 of the total stock.

We can set up the following proportion to solve for x:

78 2/5 / x = 49/200

Now, let's solve for x.

Calculation:

First, let's convert 78 2/5 to an improper fraction: 78 2/5 = (78 * 5 + 2) / 5 = 392/5

Now, we can set up the proportion: 392/5 / x = 49/200

Cross-multiply to solve for x: 392 * 200 = 5 * 49 * x 78400 = 245x

Now, solve for x: x = 78400 / 245 x ≈ 320

Answer:

So, the total amount of potatoes originally in stock was approximately 320 kilograms.
