Answer 1

 

4 целых 2\11-1целая 9\11=2 целых 4/11

6целых 4\23-(3целых-2целых8\23)+5целых16\23=11 целых 5/23

                                     задача

На базу привезли яблоки на трёх машинах.На первой машине было 3целых7\20т.Это на 15\20т меньше чем на второй машине и на 1целую16\20т больше чем на третьей.Сколько всего тонн яблок привезли на базу.

Решение

Вторая машина -3целых7\20т + 15\20т = 4 целых 2/20

Третья машина -3целых7\20 -  1целую16\20т = 1 целая 11/20

Всего тонн привезли -3целых7\20т+4 целых 2/20+1 целая 11/20= 9 тонн

Answer 2

To solve the given problem, let's break it down step by step.

Problem 1: 4 whole + 2/11 - 1 whole + 9/11

To solve this, we need to find a common denominator for the fractions. The common denominator for 11 and 1 is 11.

4 whole + 2/11 - 1 whole + 9/11 can be rewritten as: 4 + 2/11 - 1 - 9/11

Now, let's subtract the fractions: 2/11 - 9/11 = -7/11

So, the expression becomes: 4 - 1 - 7/11 = 3 - 7/11

Therefore, 4 whole + 2/11 - 1 whole + 9/11 is equal to 3 - 7/11.

Problem 2: 6 whole + 4/23 - (3 whole - 2 whole 8/23) + 5 whole 16/23

To solve this, we need to simplify the expression inside the parentheses first.

3 whole - 2 whole 8/23 can be rewritten as: 3 - 2 - 8/23 = 1 - 8/23

Now, let's simplify the expression: 6 whole + 4/23 - (1 - 8/23) + 5 whole 16/23

6 whole + 4/23 - 1 + 8/23 + 5 whole 16/23

Now, let's add the whole numbers: 6 + 5 = 11

Now, let's add the fractions: 4/23 + 8/23 = 12/23

So, the expression becomes: 11 + 12/23 - 1 + 5 whole 16/23

Now, let's add the mixed numbers: 11 + 1 + 5 = 17

So, the expression becomes: 17 + 12/23 + 5 whole 16/23

Now, let's add the fractions: 12/23 + 16/23 = 28/23

So, the expression becomes: 17 + 28/23

To simplify the expression further, we can convert the mixed number to an improper fraction: 17 + 28/23 = (17 * 23 + 28) / 23 = 391/23

Therefore, 6 whole + 4/23 - (3 whole - 2 whole 8/23) + 5 whole 16/23 is equal to 391/23.

Problem 3: Number of tons of apples brought to the base

Let's solve this problem step by step.

We are given the following information: - The first car had 3 whole 7/20 tons of apples. - The first car had 15/20 tons less than the second car. - The first car had 1 whole 16/20 tons more than the third car.

Let's find the amount of apples in the second car: The second car had 3 whole 7/20 + 15/20 = 3 whole 22/20 tons of apples.

Let's find the amount of apples in the third car: The third car had 3 whole 7/20 - 1 whole 16/20 = 1 whole 15/20 tons of apples.

Now, let's find the total amount of apples brought to the base: Total = Amount in the first car + Amount in the second car + Amount in the third car Total = 3 whole 7/20 + 3 whole 22/20 + 1 whole 15/20

Let's convert the mixed numbers to improper fractions: Total = (3 * 20 + 7)/20 + (3 * 20 + 22)/20 + (1 * 20 + 15)/20 Total = (60 + 7)/20 + (60 + 22)/20 + (20 + 15)/20 Total = 67/20 + 82/20 + 35/20

Now, let's add the fractions: Total = (67 + 82 + 35)/20 Total = 184/20

To simplify the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 4: Total = 46/5

Therefore, the total amount of tons of apples brought to the base is 46/5.
