AYUDAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Answer 1

Explicación paso a paso:

1). (6-7) + (5-2) = -1 + 3 = 2

2). (7-3) x (6-9) = 4 x -3 = -12

3). (9-6) - (5x4) = 3 - 12 = -9

4). 5 - (7-9) = 5 - (-2) = 5 + 2 = 7

5). (8-6) + (15÷$\frac{3}{4}$) = 2 + 45 = 47

6). $(\frac{1}{2} + \frac{4}{5} ) x (\frac{5}{4} - \frac{1}{2} )$ = $\frac{13}{10} x \frac{3}{4}$ = 39
