Question

2/9 - ( 3/8 + 2/5 x 8/4 ) x 3/4

Answer 1

$\frac{2}{9}-\left(\frac{3}{8}+\frac{2}{5}\cdot \frac{8}{4}\right)\cdot \frac{3}{4}$

$\frac{2}{9}-(\frac{3}{8} +\frac{4}{5})\frac{3}{4}$

$\frac{2}{9}-(\frac{47}{40})\frac{3}{4}$

$\frac{2}{9}-\frac{141}{160}=\frac{2\cdot \:160}{1440}-\frac{141\cdot \:9}{1440}=\frac{2\cdot \:160-141\cdot \:9}{1440}=-\frac{949}{1440}$
