1) 1/8 - 5/12 - (- 5/6)
= [tex] \frac{1 X 3}{8 X 3} [/tex] - [tex] \frac{5 X 2}{12 X 2} [/tex] - (- 5/6)
= 3/24 - 10/24 - (- 5/6)
= - 7/24 - (- 5/6)
= - 7/24 + 5/6
= - 7/24 + [tex] \frac{5 X 4}{6 X 4} [/tex]
= - 7/24 + 20/24
= 13/24
2) 1/8 - (- 5/12)
= 1/8 + 5/12
= [tex] \frac{1 X 3}{8 X 3} [/tex] + [tex] \frac{5 X 2}{12 X 2} [/tex]
= 3/24 + 10/24
= 13/24
