Question

1pe60:(-1pe30)-(-6pe10)

Answer 1

1/60  : (-1/30) - (-6/10) =

1/60 x ( -30) + 6/10 =

- 1/2 + 6/10 =

(-5 + 6)/10 =

1/10

Answer 2

$\frac{1}{60} : ( - \frac{1}{30}) - ( - \frac{6}{10}) = \frac{1}{60} : - \frac{1}{30} - ( - \frac{3}{5}) = \frac{1}{60} \times \frac{30}{ - 1} - ( - \frac{3}{5}) = \frac{1 \times 30}{ - 60} - ( - \frac{3}{5}) = \frac{30}{ - 60} - ( - \frac{3}{5}) = - \frac{30}{60} - ( - \frac{3}{5}) = - \frac{1}{2} - ( - \frac{3}{5}) = - \frac{1}{2} + \frac{3}{5} = \frac{1}{10}$
