Answer 1

1 кг 200 г=1200 г.
5х+х=1200.
6х=1200.
х=200 г.

Answer 2

Calculating the Weight of the Cake

To find the weight of the cake, we can set up a system of equations based on the given information. Let's denote the weight of the cake as x and the weight of the bread as y.

Given: - x + y = 1200g (1kg 200g) - x = (1/5)y (the cake is 5 times lighter than the bread)

Solving the Equations

We can solve the system of equations to find the weight of the cake.

Substituting the second equation into the first equation: 1/5y + y = 1200g

Combining the terms: 6/5y = 1200g

Multiplying both sides by 5/6 to solve for y: y = 1000g

Now that we have the weight of the bread, we can find the weight of the cake using the second equation: x = (1/5)y x = (1/5) * 1000g x = 200g

Answer

So, the weight of the cake is 200g.
