Question

-(9,4/13+3,5/26)+6,4/13

Answer 1

=-9 4/13+6 4/13=-3
-3-3 5/26=-6 5/26

Answer 2

To solve the expression -(9,4/13 + 3,5/26) + 6,4/13, we'll follow the order of operations (PEMDAS/BODMAS):

1. First, we'll simplify the addition inside the parentheses: 9,4/13 + 3,5/26

To add fractions, we need a common denominator. The common denominator in this case is 13 * 26 = 338.

(9 * 26 + 3.5 * 13) / 338 (234 + 45.5) / 338 279.5 / 338

2. Now, let's simplify the expression -(279.5 / 338):

   -279.5 / 338

3. Finally, we'll add 6.4/13 to the result:

   -279.5 / 338 + 6.4/13

To add fractions, we need a common denominator, which is 338 * 13 = 4394.

(-279.5 * 13 + 6.4 * 338) / 4394 (-3633.5 + 2169.2) / 4394 -1464.3 / 4394

So, the simplified expression -(9,4/13 + 3,5/26) + 6,4/13 is approximately equal to -1464.3 / 4394.
