Question

Как решить пример с дробями, 5 2/3 : 1/3 - 1 7/12 *(умножить) 6Плис<3​

Answer 1

Ответ:

Найдем значение данного выражения 5 2/3 : 1/3 - 1 7/12 * 6 по действиям (сначала частное и произведение, затем разность):

1) 5 2/3 : 1/3 = (переведем первую смешанную дробь в неправильную) = 17/3 : 1/3 = (деление заменим на умножение, перевернув вторую дробь) = 17/3 * 3 = (17 * 3)/3 = (17 * 1)/1 = 17/1 = 17;

2) 1 7/12 * 6 = 19/12 * 6 = (19 * 6)/12 = (19 * 1)/2 = 19/2 = (выделим целую часть) = 9 1/2;

3) 17 - 9 1/2 = 16 2/2 - 9 1/2 = 7 1/2.

Следовательно значение выражения 5 2/3 : 1/3 - 1 7/12 * 6 = 7 1/2.

Ответ: 7 1/2.

Answer 2

Solving a Fraction Problem with Multiplication

To solve the given expression involving fractions, we can follow these steps:

1. Convert Mixed Numbers to Improper Fractions: - Convert the mixed numbers 5 2/3 and 1 7/12 to improper fractions.

2. Perform Subtraction: - Subtract the improper fraction 1/3 from the improper fraction 1 7/12.

3. Perform Multiplication: - Multiply the result from the subtraction by 6.

Let's proceed with these steps.

Step 1: Convert Mixed Numbers to Improper Fractions

To convert the mixed numbers to improper fractions: - 5 2/3 = (5 * 3 + 2) / 3 = 17/3 - 1 7/12 = (1 * 12 + 7) / 12 = 19/12

Step 2: Perform Subtraction

Now, let's subtract 1/3 from 19/12: - 19/12 - 1/3 = (19/12) - (4/12) = 15/12 = 5/4

Step 3: Perform Multiplication

Finally, let's multiply 5/4 by 6: - 5/4 * 6 = 5/4 * 6/1 = 30/4 = 7 2/4 = 7 1/2

So, the result of the given expression is 7 1/2.
