Question

como resolver 5/3.6/4+3/2 dividido 2/3 - 4/9

Answer 1

$\frac{5}{3}* \frac{6}{4}+ \frac{3}{2}: \frac{2}{3}- \frac{4}{9}= \frac{5*6}{3*4}+ \frac{3*3}{2*2}- \frac{4}{9}= \frac{30}{12}+ \frac{9}{4}- \frac{4}{9}= \frac{30*3}{12*3}+ \frac{9*9}{4*9}- \frac{4*4}{9*4}= \\ \\ = \frac{90}{36}+ \frac{81}{36}- \frac{16}{36}= \frac{90+81-16}{36}= \boxed{ \frac{155}{36}}$
