Answer 1

ans is - 0.23489711934

Answer 2

$\frac{1 }{4} \times ( \frac{8}{9} - \frac{12}{15} ) = ( \frac{1}{4} \times \frac{8}{9} ) - ( \frac{1}{4} \times \frac{12}{15} ) \\ \frac{1}{4} \times \frac{4}{45} = \frac{2}{9} - \frac{3}{15} \\ \frac{1}{45} = \frac{2}{9} - \frac{1}{5} \\ \frac{1}{45} = \frac{1}{45}$
