Question

I need to know the answer I’m working on rational numubers

Answer 1

Fraction Form:
`(11)/(24)`

Decimal Form: 0.4583

Explanation:

Apply the fraction rule:
`(-a)/(b) = - (a)/(b)`

`(-5)/(12) = - (5)/(12)`

`- (5)/(12) + (7)/(8)`

Least Common Multiple (LCM) of 12 and 8: 24

`- (5)/(12) x (2)/(2) = - (10)/(24) \\\\(7)/(8) x (3)/(3) = (21)/(24) \\\\- (10)/(24) + (21)/(24)`

Apply the fraction rule:

`(a)/(c) + (b)/(c)= (a + b)/(c)\\\\(-10 + 21)/(24) \\\\-10 + 21 = 11\\\\(11)/(24)`
