Question

Масса сушёных яблок составляет 15% массы свежих яблок. Сколько надо взять свежих яблок, чтобы получить 4,2 т сушёных? Сколько сушёных яблок получится из 5,3 т свежих яблок?

Answer 1

1) х тонн - надо взять свежих яблок,
тогда
х/100*15=4,2 т
х=4,2*100/15
х=28 т (свеж. яблок надо взять, чтобы получить 4,2 т сушеных

2) из 5,3 т свежих получится = 5,3 /100 * 15 = 0,795 т или 795 кг

Answer 2

Calculation 1: How many fresh apples are needed to obtain 4.2 tons of dried apples?

To calculate the number of fresh apples needed to obtain 4.2 tons of dried apples, we need to consider that the dried apples make up 15% of the weight of the fresh apples.

Let's assume the weight of the fresh apples needed is x tons. Since the dried apples make up 15% of the weight of the fresh apples, we can set up the following equation:

0.15x = 4.2

To solve for x, we divide both sides of the equation by 0.15:

x = 4.2 / 0.15

Calculating this, we find that x is approximately 28 tons.

Therefore, you would need to take approximately 28 tons of fresh apples to obtain 4.2 tons of dried apples.

Calculation 2: How many dried apples can be obtained from 5.3 tons of fresh apples?

To calculate the number of dried apples that can be obtained from 5.3 tons of fresh apples, we again consider that the dried apples make up 15% of the weight of the fresh apples.

Let's assume the weight of the dried apples obtained is y tons. Since the dried apples make up 15% of the weight of the fresh apples, we can set up the following equation:

0.15 * 5.3 = y

Calculating this, we find that y is approximately 0.795 tons.

Therefore, you would obtain approximately 0.795 tons of dried apples from 5.3 tons of fresh apples.

Please note that these calculations are approximate and may vary depending on the specific weight and moisture content of the apples.
