Пошаговое объяснение:

1) 6 4/13 * 2 5/27 = 82/13 * 59/27 = 4838/351 =

13 275/351.

2) 4 3/13 * 2 2/27 = 55/13 * 56/27 = 3080/351 = 8 272/351

3) 13 275/351 - 8 272/351 = 5 3/351 = 5 1/117

Answer 3

To calculate the expression:

6 4/13 * 2 5/27 - 4 3/13 * 2 2/27

First, let's convert the mixed numbers to improper fractions:

6 4/13 = (6 * 13 + 4) / 13 = 82/13 2 5/27 = (2 * 27 + 5) / 27 = 59/27 4 3/13 = (4 * 13 + 3) / 13 = 55/13 2 2/27 = (2 * 27 + 2) / 27 = 56/27

Now, the expression becomes:

(82/13) * (59/27) - (55/13) * (56/27)

To perform the multiplication and subtraction, find a common denominator, which is 13 * 27 = 351:

[(82/13) * (59/27)] = (82 * 59) / (13 * 27) = 4838/351 [(55/13) * (56/27)] = (55 * 56) / (13 * 27) = 3080/351

Now, subtract the second fraction from the first:

(4838/351) - (3080/351) = (4838 - 3080) / 351 = 1758/351

Now, simplify the fraction by finding the greatest common divisor (GCD) of 1758 and 351, which is 9:

(1758/351) ÷ 9 = (195/39) ÷ 9 = 13/3

So, the result of the expression is 13/3 or 4 1/3 in mixed number form.
