Answer 1

 если модули то их Вам надо перевести в числа и решить:
1)   |-7| - |-3,6| : |1,2| = 7 - 3,6 : 1,2 = 7 - 4 = 3
2)   |6(целых)3/7| : |-9| + 4(целых)1/3  = 45/7 * 1/9 + 13/3 = 5 целых 1/21
3)   |-7/24| * |-1(целая) 1/7| *3 = 7/24 *  8/7 * 3 = 1
4)   |2,7| : |-1(целая) 4/5| * |1(целую) 5/9| = 27/10 * 5/9 * 14/9 = 2 целых 1/3

Answer 2

1) To solve the expression |-7| + |-3.6| + |1.2|, we need to find the absolute value of each number and then add them together.

The absolute value of a number is its distance from zero on the number line. It is always a non-negative value.

|-7| = 7 |-3.6| = 3.6 |1.2| = 1.2

So, |-7| + |-3.6| + |1.2| = 7 + 3.6 + 1.2 = 11.8

2) To solve the expression 6(целых)3/7 : |-9| + +4(целых)1/3, we need to perform the operations in the correct order.

First, let's simplify the expression |-9| = 9.

Now, we have 6(целых)3/7 : 9 + 4(целых)1/3.

To divide a mixed number by a whole number, we need to convert the mixed number to an improper fraction.

6(целых)3/7 = (6 * 7 + 3)/7 = 45/7

So, the expression becomes 45/7 : 9 + 4(целых)1/3.

To divide a fraction by a whole number, we multiply the fraction by the reciprocal of the whole number.

45/7 : 9 = 45/7 * 1/9 = 45/63 = 5/7

Now, the expression becomes 5/7 + 4(целых)1/3.

To add a mixed number to a fraction, we need to convert the mixed number to an improper fraction.

4(целых)1/3 = (4 * 3 + 1)/3 = 13/3

So, the expression becomes 5/7 + 13/3.

To add fractions, we need to have a common denominator. The least common
