Пошаговое объяснение:

1) 5/6+x=1 12/17

х= 29/17 - 5/6

х=174/104 - 85/104

х= 89/104

2) 1/3х=2/5

3) 5/6 : х = 1/4

х= 5/6 * 4

х= 20/6

х= 3 1/3

4) 0,3х=4, 5

х= 4,5 : 0,3

х= 15

5) х:2/15=3

х= 3 * 2/15

х= 2/5

6) 6/13х=39

х= 39 * 13/6

х= 84 1/2

7) х :1/4=5

х= 5 * 1/4

х= 1/1/4

8) 1/6:х=2/5

х= 1/6 * 5/2

х= 5/12

9) х :3/7=1/49

х= 1/49 * 3/7

х=3/343

Answer 2

Solving the Equations:

1) Equation: 5/6 + x = 1 + 12/17

To solve this equation, we need to isolate the variable x on one side of the equation. Let's start by simplifying the equation:

5/6 + x = 1 + 12/17

To add fractions, we need a common denominator. In this case, the least common multiple of 6 and 17 is 102. Let's rewrite the equation with the common denominator:

(5/6)(17/17) + x = (1)(17/17) + (12/17)(6/6)

(85/102) + x = 17/17 + 72/102

Now, let's simplify further:

85/102 + x = 17/17 + 72/102

85/102 + x = 102/102 + 72/102

85/102 + x = 174/102

To isolate x, we subtract 85/102 from both sides:

x = 174/102 - 85/102

x = (174 - 85)/102

x = 89/102

Therefore, the solution to the equation is x = 89/102.
