Свойства деления Вычисли. Примени правило деления числа на произведение.81 : 27 =: (9 ⋅ 3) = 64 : 16 =дайте пожалуйста ответ!​

Answer 1

Пошаговое объяснение:

Полное условие во вложении.

Свойство деления на произведение : чтобы разделить число на произведение, нужно разделить это число на первый сомножитель, а полученный результат разделить на второй сомножитель.

a : ( b * c )=( a : b ) : c

1) 81 : 27 = 81 : ( 9 * 3)= (81 :9 ) : 3= 9 :3= 3

2) 64 : 16 = 64 : ( 8 * 2) = ( 64 : 8) : 2 = 8 : 2 = 4

Answer 2

Properties of Division

Division is an arithmetic operation that involves splitting a number into equal parts or groups. When dividing one number by another, there are several properties that can be applied to simplify the calculation. One of these properties is the rule of dividing a number by a product.

Rule of Dividing a Number by a Product

The rule of dividing a number by a product states that you can divide a number by a product of two or more numbers by dividing the number by each of the individual factors and then multiplying the results together.

For example, let's calculate the division of 81 by 27 using the rule of dividing a number by a product:

Step 1: Divide 81 by 9: 81 ÷ 9 = 9

Step 2: Divide 27 by 3: 27 ÷ 3 = 9

Step 3: Multiply the results together: 9 × 9 = 81

Therefore, 81 ÷ 27 = 9.

In this case, we divided 81 by the product of 9 and 3, which are the factors of 27. The result is 9, which is the same as dividing 81 by 27 directly.

Calculation:

Let's apply the rule of dividing a number by a product to calculate the division of 81 by 27:

81 ÷ 27 = (9 × 3) = 9

Therefore, the result of dividing 81 by 27 is 9.
