Срочноооооооооо!!!!! 1)1 1/9 * 3/10 = Распишите полностью 2) 20-( 3 1/6 + 32 3/4) = 3) 4/11 * 4 7/12

Answer 1

1)11/9*3/10=33/90=11/30
2) 20-(3 1/6+32 3/4)=20-35 11/12=-15 11/12
3) 4/11*4 7/12= 4 7/33

Answer 2

1) 9 и 3 сокращаем
получается 11/30
2) приводим к одинаковому знаменателю(12) складываем= 35 11/12
из 20 - 35 11/12=-15 11/12
3) сокращаем все , т.е . 4*55/ 11*12= 1 2/3

Answer 3

1) Решим задачу по порядку действий. Сначала выполним сложение 1 и 1/9:

1 + 1/9 = 9/9 + 1/9 = 10/9.

Затем умножим полученную сумму на 3/10:

10/9 * 3/10 = (10 * 3) / (9 * 10) = 30/90 = 1/3.

Итак, результат выражения 1 + 1/9 * 3/10 равен 1/3.

2) Теперь рассмотрим выражение 20 - (3 + 1/6 + 32 + 3/4). Сначала выполним сложение в скобках:

3 + 1/6 = 18/6 + 1/6 = 19/6.

32 + 3/4 = 128/4 + 3/4 = 131/4.

Теперь выражение примет вид:

20 - (19/6 + 131/4).

Для выполнения вычитания необходимо привести дроби к общему знаменателю:

19/6 = (19 * 4) / (6 * 4) = 76/24.

131/4 = (131 * 6) / (4 * 6) = 786/24.

Теперь выражение будет выглядеть так:

20 - (76/24 + 786/24).

Сложим дроби в скобках:

76/24 + 786/24 = 862/24.

Теперь выполним вычитание:

20 - 862/24 = (20 * 24) / 24 - 862/24 = (480 - 862) / 24 = -382/24.

Итак, результат выражения 20 - (3 + 1/6 + 32 + 3/4) равен -382/24.

3) Рассмотрим выражение 4/11 * (4 + 7/12). Сначала выполним сложение в скобках:

4 + 7/12 = 48/12 + 7/12 = 55/12.

Теперь выражение будет выглядеть так:

4/11 * (55/12).

Умножим дроби:

4/11 * 55/12 = (4 * 55) / (11 * 12) = 220/132.

Дробь 220/132 можно сократить на их НОД, который равен 4:

220/132 = (220/4) / (132/4) = 55/33.

Итак, результат выражения 4/11 * 4 + 7/12 равен 55/33.

Answer 4

1) To solve the expression 1 + 1/9 * 3/10, we need to follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, we have multiplication and addition.

First, we perform the multiplication: 1/9 * 3/10 = 3/90 = 1/30.

Then, we perform the addition: 1 + 1/30 = 30/30 + 1/30 = 31/30.

Therefore, the value of the expression 1 + 1/9 * 3/10 is 31/30.

2) To solve the expression 20 - (3 + 1/6 + 32 + 3/4), we again need to follow the order of operations.

First, we perform the addition inside the parentheses: 3 + 1/6 + 32 + 3/4 = 3 + 1/6 + 32 + 3/4 = 3 + 1/6 + 32 + 9/12.

Next, we simplify the fractions: 1/6 = 2/12 and 9/12 = 3/4.

Now, we can rewrite the expression: 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 + 32 + 3/4) = 20 - (3 + 2/12 +
