Question

В вишневом варенье отношение массы вишни к массе сахара равно 2:3.сколько килограммов вишни и сколько килограмов сахара в 3'5 кг вишневого варенья?

Answer 1

Принимаем общую массу варенья за 5 частей. Тогда масса 1 части равна 3,5/5=0,7кг. Вишни 2 части - значит 2*0,7=1,4; сахара 3 части - 3*0,7=2,1

Answer 2

Calculation of Cherry and Sugar Mass in Cherry Jam

To calculate the mass of cherries and sugar in 3.5 kg of cherry jam, we need to use the given ratio of cherry mass to sugar mass, which is 2:3.

Let's assume the mass of cherries is 2x kg and the mass of sugar is 3x kg, where x is a constant.

According to the given ratio, we have the equation:

2x : 3x = 2 : 3

To find the value of x, we can set up a proportion:

2x / 3x = 2 / 3

Cross-multiplying, we get:

2x * 3 = 3x * 2

Simplifying, we have:

6x = 6x

This equation is true for any value of x. Therefore, we can choose any value for x.

Let's assume x = 1 for simplicity.

Now, we can calculate the mass of cherries and sugar in 3.5 kg of cherry jam.

The mass of cherries is 2x = 2 * 1 = 2 kg.

The mass of sugar is 3x = 3 * 1 = 3 kg.

Therefore, in 3.5 kg of cherry jam, there are 2 kg of cherries and 3 kg of sugar.

Answer:

In 3.5 kg of cherry jam, there are 2 kg of cherries and 3 kg of sugar.
