Постараюсь тебе помочь.
И так:
Во-первых, найдем сколько купила листов Лида:
120:3*1=40
Далее, найдем сколько купила листов Нина:
120:4*1=30
Потом, на сколько больше купила листьев Лида:
40-30=10
Переводим грн в копейки
т.е. 2грн=200 копейки (2*100=200)
Таким образом, найдем сколько стоит один лист
200:10=20
Ответ: 20 коп. стоит один лист

msyuliyash: Пожалуйста! Всегда рада помочь.

Johann Heinrich Pestalozzi
Johann Heinrich Pestalozzi (January 12, 1746 – February 17, 1827) was a Swiss pedagogue and educational reformer, who greatly influenced the development of the educational system in Europe and America. Pestalozzi’s method became widely accepted, and most of his principles have been absorbed into modern elementary education.
He presented two general purposes of education: for development of the individual and for the improvement of society.
Pestalozzi asserted that education should be centered on the child, not the curriculum. Since knowledge lies within human beings, the purpose of teaching is to find the way to unfold that hidden knowledge. Pestalozzi advocated direct experience as the best method to accomplish this. He also advocated spontaneity and self-activity, in contrast to the teacher-centered and curriculum-based methods used in other schools.
He advocated an inductive method, in which the child first learns to observe, to correct its own mistakes, and to analyze and describe the object of inquiry. The child starts with simple objects and simple observation, and builds toward more complex and abstract things. Only after that can the child start to use books.
In order to allow children to obtain more experience from nature, Pestalozzi expanded the elementary school curriculum to include geography, natural science, fine art, and music.
Pestalozzi maintained that the classroom should be like a family. The atmosphere must be loving and caring, like in a good Christian family, where the family members are cooperative, loving, and kind to one another.
Based on this assumption, Pestalozzi suggested that teachers always need to be loving and kind, and earn the trust of the children.
