Here is an example of a problem. )
In a pan with a diameter of 36 cm, 10 pancakes can be baked from one serving of dough. Estimate how many pancakes it would be possible to bake if we took a frying pan with a diameter of 24 cm. (Round to the nearest integer)

Answer 1

Well look. We have a test volume. The consumption of dough for a pancake is directly proportional to the area of ​​\u200b\u200bthis pancake. And the number of pancakes from the same amount of dough is inversely proportional to the consumption of dough for one pancake. And the area of ​​​​the pancake depends on the diameter of the pan ... It seems that there is nowhere to suggest further :)
