Answer 1

7 5/6-4 2/3=7 5/6-4 4/6=3 1/6
----------------------
10 4/9-8 5/18=10 8/18-8 5/18=2 3/18=2 1/6

Answer 2

2) 7 целых 5/6 - 4 целых 2/3 + 4 =

To begin, let's simplify the fractions: 7 целых 5/6 = (7 * 6 + 5) / 6 = 47/6 4 целых 2/3 = (4 * 3 + 2) / 3 = 14/3

Now, we can substitute these values back into the equation: 47/6 - 14/3 + 4

To add or subtract fractions, we need to have a common denominator. In this case, the common denominator is 6. Let's convert 14/3 to have a denominator of 6: 14/3 * 2/2 = 28/6

Now, we can rewrite the equation as: 47/6 - 28/6 + 4

Subtract the numerators: (47 - 28)/6 + 4 = 19/6 + 4

To add fractions, they need to have a common denominator. In this case, the common denominator is 6, so we need to convert 4 to have a denominator of 6: 4 * 6/6 = 24/6

Now, we can rewrite the equation as: 19/6 + 24/6

Add the numerators: (19 + 24)/6 = 43/6

Therefore, 2) 7 целых 5/6 - 4 целых 2/3 + 4 = 43/6.
