Question

-1/2*4/7+3/7:15/14

Answer 1

\(\dfrac{-1}{2}x\dfrac{4}{7}+\dfrac{3}{7}:\dfrac{15}{14}=\dfrac{-2}{7}+\dfrac{3}{7}x\dfrac{14}{15}=\dfrac{-2}{7}+\dfrac{2}{5}=\dfrac{4}{35}\)

Answer 2

`[-1] / 2 xx 4 / 7 + 3 / 7 : 15 / 14`

`= [ -1 xx 2 xx 2 ] / [ 2 xx 7 ] + 3 / 7 xx 14 / 15`

`= [-2] / 7 + [ 3 xx 2 xx 7 ] / [ 7 xx 3 xx 5 ]`

`= [-2] / 7 + 2 / 5`

`= [4] / 35`
