Question

Answer 1

`1/3 + 3/8 - 7/12`

`=8/24+9/24-14/24`

`=(8+9-14)/24`

`=3/24`

`=1/8`

___________________________

`1/4 - 2/3 - 11/18`

`=9/36 - 24/36 - 22/36`

`=(9-24-22)/36`

`=-37/36`

________________________

`7/9 +5/12-3/4`

`=28/36 + 15/35 - 27/36`

`=(28+15-27)/36`

`=16/36`

`=4/9`

Answer 2

\(\dfrac{1}{3}+\dfrac{3}{8}-\dfrac{7}{12}=\dfrac{8}{24}+\dfrac{9}{24}-\dfrac{14}{24}=\dfrac{3}{24}=\dfrac{1}{8}\)

\(\dfrac{1}{4}-\dfrac{2}{3}-\dfrac{11}{18}=\dfrac{9}{36}-\dfrac{24}{36}-\dfrac{22}{36}=-\dfrac{37}{36}\)

\(\dfrac{7}{9}+\dfrac{5}{12}-\dfrac{3}{4}=\dfrac{28}{36}+\dfrac{15}{36}-\dfrac{27}{36}=\dfrac{16}{36}=\dfrac{4}{9}\)
