Question

6+(−4 3/4)+(−2 1/8) i need help this is home work please

Answer 1

`6 + ( - 4 (3)/(4) ) + ( - 2 (1)/(8) ) \\ \\ = 6 - 4 (3)/(4) - 2 (1)/(8)`


`= 6 - (4 * 4 + 3)/(4) - (2 * 8 + 1)/(8) \\ \\ = 6 - (19)/(4) - (17)/(8)`


`= (6 * 8 - 19 * 2 - 17 * 1)/(8) \\ \\ = (48 - 38 - 17)/(8)`


`= (48 - (38 + 17))/(8) \\ \\ = (48 - 55)/(8) \\ \\ = \boxed{ ( - 7)/(8) }`
