Question

Мальчик и девочка рвали в лесу орехи. Всего они сорвали 120 штук. Девочка сорвала в 2 раза меньше мальчика. Сколько орехов было у мальчика и девочки в отдельности?

Answer 1

Если у девочки одна часть, то у мальчика 2 части.
1) 2 + 1 = 3 (части) -всего
2) 120 : 3 = 40 ( ор) - в одной части или у девочки
3) 40 * 2 = 80 (ор) - у мальчика или 120 - 40= 80 (ор)

Answer 2

Answer in detail. A boy and a girl were picking nuts in the forest. They picked 120 nuts in total. The girl picked 2 times less than the boy. How many nuts did the boy and the girl have separately?

To answer this question, we can use the following steps:

- Let x be the number of nuts that the boy picked. Then, the number of nuts that the girl picked is x/2, since she picked 2 times less than the boy. - The total number of nuts that they picked is 120, so we can write an equation: x + x/2 = 120 - To solve for x, we need to multiply both sides of the equation by 2, to get rid of the fraction: 2x + x = 240 - Simplify and combine like terms: 3x = 240 - Divide both sides by 3, to isolate x: x = 240/3 - Simplify: x = 80 - Therefore, the boy picked 80 nuts and the girl picked 80/2 = 40 nuts.
