Question

Прравила деления десятичных дробей

Answer 1

Чтобы разделить на десятичную дробь, нужно и в делимом, и в делителе перенести запятую на столько цифр вправо, сколько их после запятой в делителе, то есть, на один знак. Получаем: 35,1 : 1,8 =351 : 18. Теперь выполняем деление уголком. В итоге получаем: 35,1 : 1,8 = 19,5.

Rules for Dividing Decimal Fractions

When dividing decimal fractions, the following rules apply:

1. Place the decimal point in the quotient: When dividing decimal fractions, the decimal point in the quotient should be placed directly above the decimal point in the dividend. For example, when dividing 0.25 by 0.5, the decimal point in the quotient should be directly above the decimal point in 0.25.

2. Move the decimal point to the right: To divide by a decimal fraction, move the decimal point to the right until it becomes a whole number. Then, move the decimal point in the dividend the same number of places to the right. For example, when dividing 0.6 by 0.2, both the dividend and the divisor should be multiplied by 10 to make the divisor a whole number.

3. Perform the division: Once the decimal point has been moved, perform the division as you would with whole numbers. For example, when dividing 1.45 by 1.23, perform the division as you would with whole numbers, and then place the decimal point in the quotient directly above the decimal point in the dividend.

4. Carry out the division: When dividing decimal fractions, carry out the division as you would with whole numbers, and then place the decimal point in the quotient directly above the decimal point in the dividend. For example, when dividing 3.2 by 1.8, perform the division as you would with whole numbers, and then place the decimal point in the quotient directly above the decimal point in the dividend.

5. Check the result: After performing the division, it's important to check the result to ensure accuracy. For example, when dividing 306 by 3, the result should be 102. After performing the division, it's important to check the result to ensure accuracy.

These rules provide a systematic approach to dividing decimal fractions, ensuring accuracy and consistency in the division process.
