Question

Масса груши и яблока 340г, а груши и лимона-250г, Масса всех трёх фруктов- 480г. Какова масса лимона? Какова масса яблока?, Какова масса груши?. Масса какого фрукта меньше: лимона или груши?. На сколько грамов меньше?

Answer 1

480-250=230(гр)весит Яблоко
340-230=110(гр)весит груша
250-110=140(гр)весит лимон
1)груши 2)на30

Answer 2

Calculation of Fruit Masses:

To calculate the mass of the lemon, apple, and pear, we can set up a system of equations based on the given information.

Let's denote the mass of the pear as P, the mass of the apple as A, and the mass of the lemon as L.

From the given information, we have the following equations:

1. P + A = 340g (Equation 1) 2. P + L = 250g (Equation 2) 3. P + A + L = 480g (Equation 3)

To find the mass of the lemon, we can subtract Equation 2 from Equation 3:

P + A + L - (P + L) = 480g - 250g

Simplifying the equation, we get:

A = 230g

Therefore, the mass of the lemon is 230g.

To find the mass of the apple, we can subtract Equation 1 from Equation 3:

P + A + L - (P + A) = 480g - 340g

Simplifying the equation, we get:

L = 140g

Therefore, the mass of the apple is 140g.

To find the mass of the pear, we can substitute the values of the lemon and apple into Equation 1:

P + 140g = 340g

Simplifying the equation, we get:

P = 200g

Therefore, the mass of the pear is 200g.

Comparison of Lemon and Pear Masses:

To determine which fruit has a smaller mass, we compare the mass of the lemon and the pear.

The mass of the lemon is 230g, and the mass of the pear is 200g.

Therefore, the mass of the pear is 30g less than the mass of the lemon.

In summary: - The mass of the lemon is 230g. - The mass of the apple is 140g. - The mass of the pear is 200g. - The mass of the pear is 30g less than the mass of the lemon.
