Question

(2/15+7/12)*30/45-(2:2 1/2)*5/32​

Answer 1

$( \frac{2}{15} + \frac{7}{12}) \times \frac{30}{45} - (2 \div 2 \frac{1}{2}) \times \frac{5}{32}$

$\frac{43}{60} \times \frac{30}{45} - (2 \div \frac{5}{2}) \times \frac{5}{32}$

$\frac{43}{2} \times \frac{1}{45} - (2 \times \frac{2}{5}) \times \frac{5}{32}$

$\frac{43}{90} - \frac{4}{5} \times \frac{5}{32}$

$\frac{43}{90} - \frac{1}{8}$

$\frac{127}{360}$
