Question

5 1/6-(а+1 7/9)= а=1,6

Answer 1

1) 6- ( 8/5 + 17/9 ) = 3 целых 31\45
2) 51 * 45 / 166 = 13 целых 127/166

Answer 2

5 + 1/6 - (a + 1 + 7/9) = a + 1.6

First, let's simplify the left side of the equation:

5 + 1/6 - (a + 1 + 7/9) = a + 1.6 Convert 5 to a fraction with a common denominator of 6: 30/6 + 1/6 - (a + 1 + 7/9) = a + 1.6 Combine the fractions: 31/6 - (a + 1 + 7/9) = a + 1.6

Now, let's simplify the right side of the equation:

a = 1.6

Now, we can substitute a = 1.6 into the left side of the equation:

31/6 - (1.6 + 1 + 7/9) = 1.6 + 1.6 31/6 - (3.6 + 7/9) = 3.2

To simplify further, we need to find a common denominator for 6 and 9, which is 18:

31/6 - (18/5 + 14/18) = 3.2 31/6 - (162/90 + 70/90) = 3.2 31/6 - 232/90 = 3.2

Now, let's combine the fractions:

31/6 - 232/90 = 3.2 Multiply 31/6 by 15/15 to get a common denominator: 465/90 - 232/90 = 3.2 Combine the fractions: 233/90 = 3.2

Since 233/90 is not equal to 3.2, we can conclude that a = 1.6 does not satisfy the original equation. Therefore, there is no solution for a that satisfies the given equation.
