Пошаговое объяснение:

4 2/3 *2 1/5+2 1/5*1/3-5*1 1/5= 2 1/5 *(4 2/3 + 1/3) - 5 * 1 1/5 = 2 1/5 * 5 - 5 * 1 1/5 = 5 *(2 1/5 - 1 1/5 ) = 5 * 1 = 5

Answer 2

To simplify the expression 4 2/3 * 2 1/5 + 2 1/5 * 1/3 - 5 * 1 1/5, we can follow these steps:

Step 1: Convert mixed numbers to improper fractions. 4 2/3 can be converted to an improper fraction as follows: 4 2/3 = (4 * 3 + 2)/3 = 14/3

2 1/5 can be converted to an improper fraction as follows: 2 1/5 = (2 * 5 + 1)/5 = 11/5

1 1/5 can be converted to an improper fraction as follows: 1 1/5 = (1 * 5 + 1)/5 = 6/5

Step 2: Perform the operations using the improper fractions. Now, the expression becomes: (14/3) * (11/5) + (11/5) * (1/3) - 5 * (6/5)

Step 3: Simplify each term. (14/3) * (11/5) = 154/15 (11/5) * (1/3) = 11/15 5 * (6/5) = 30/5 = 6

Step 4: Combine the simplified terms. 154/15 + 11/15 - 6

Step 5: Find a common denominator (which is 15 in this case) and combine the fractions: (154 + 11)/15 - 6 = 165/15 - 6

Step 6: Simplify the result: 165/15 is an improper fraction that can be simplified as follows: 165 ÷ 15 = 11

So, the final answer is 11 - 6 = 5.
