Question

Больному прописано лекарство,которое нужно принемать по 0,5 г 2 раза в день в течении 7 дней. В одной упаковке 10 таблеток по 0,25 г. Какого наибольшего количества упаковок хватит на весь курс лечения?

Answer 1

0.5 * 2 = 1г - нужно принимать в день

1 * 7 = 7г - нужно принять за 7 дней

0,25 * 10 = 2,5г - в одной упаковке таблеток

7 : 2,5 = 2,8 упаковок нужно на весь курс

2,8 упаковок никто не продаст, так что необходимо купить 3 упаковки таблеток

Answer 2

Calculating the Required Medication

To calculate the number of packages needed for the entire course of treatment, we can follow these steps:

1. Dosage Information: - The prescribed medication needs to be taken at a dosage of 0.5g, twice a day, for 7 days.

2. Tablet Strength: - Each tablet in the package has a strength of 0.25g.

3. Calculating the Total Required Medication: - We need to find out how many tablets are needed for the entire course of treatment.

Calculation

To calculate the total number of tablets needed for the entire course of treatment, we can use the following formula:

Total dosage needed = Dosage per day * Number of days

Given: - Dosage per day = 0.5g - Number of days = 7

Total dosage needed = 0.5g * 2 * 7 = 7g

Now, we need to find out how many tablets are needed to achieve a total dosage of 7g.

Each tablet has a strength of 0.25g, so the number of tablets needed can be calculated as:

Number of tablets needed = Total dosage needed / Tablet strength

Number of tablets needed = 7g / 0.25g = 28 tablets

Determining the Number of Packages Required

Since each package contains 10 tablets, we can calculate the number of packages needed as follows:

Number of packages needed = Number of tablets needed / Tablets per package

Number of packages needed = 28 tablets / 10 tablets per package = 2.8

As we cannot purchase a fraction of a package, we would need to round up to the nearest whole number. Therefore, 3 packages would be required to complete the entire course of treatment.

So, the answer is: 3 packages would be needed for the entire course of treatment.
