Answer 1

7*3=21
7+21=28
28*5=140
Ответ: виноградин 140 штук

Answer 2

Апельсина-7
мандарина- в 3 > чем апельсина
винограда-в 5 раз больше чем апелисинов и мандвринов вместе
всего-? фрукт.
7*3=21
21+7=28 апелсин и мандарин
28*5=140 (винограда)
140+7+21=168 (фруктов)всего

Answer 3

Task Solution:

To solve the problem, we'll first calculate the number of grapes in the vase and then determine the total number of fruits.

Let's start by calculating the number of grapes in the vase.

1. Calculate the Number of Grapes: - Number of Oranges: 7 - Number of Tangerines: 3 times the number of Oranges - Number of Grapes: 5 times the total of Oranges and Tangerines

We can represent the number of oranges as "o", the number of tangerines as "t", and the number of grapes as "g". We have the following equations: - t = 3o - g = 5(o + t)

Substituting the value of t from the first equation into the second equation, we get: - g = 5(o + 3o) - g = 5(4o) - g = 20o

This means the number of grapes is 20 times the number of oranges.

2. Calculate the Total Number of Fruits: - Total number of fruits = Number of Oranges + Number of Tangerines + Number of Grapes

Substituting the value of t (3o) and g (20o) into the equation, we get: - Total number of fruits = o + 3o + 20o - Total number of fruits = 24o

This means the total number of fruits is 24 times the number of oranges.

3. Solving for the Number of Grapes and Total Fruits: - Given that there were 7 oranges, we can calculate the number of grapes and the total number of fruits.

Calculation:

- Number of Oranges (o) = 7 - Number of Tangerines (t) = 3 * 7 = 21 - Number of Grapes (g) = 20 * 7 = 140 - Total Number of Fruits = 24 * 7 = 168

So, there were 140 grapes and a total of 168 fruits in the vase.
