Question

{(-1/5*3/4) + (6/7*-9/20)} + {(10/9 ÷ 5/18 * 6/11) + (-6/11 * 7/10)}​

Answer 1

Answer: 187/40

Step-by-step explanation:

-1/5 * 3/4 = -3/20

6/7 * -9/20 = -54/140

10/9 / 5/18 * 6/11 = 2/1 * 2/1 * 6/11 = 24/11

-3/11 * 7/5 = -21/55

-3/20 + (-54/140) + (24/11) + (-21/55)

-21/140 - 54/140 = -65/140

120/55 -21/55 = 99/55 = 9/5

-65/140 + 252/140 = 187 / 140
