Question

quero saber como calcular a expressão 1/2.3/4+1/5.3/2

Answer 1

$\frac{1}{2}.\frac{3}{4}+\frac{1}{5}.\frac{3}{2}= \\ \\ \boxed{\frac{3}{8}+\frac{3}{10}=\frac{15+12}{40}=\frac{27}{40}}$

Answer 2

$\frac{1}{2} . \frac{3}{4} + \frac{1}{5} . \frac{3}{2} = \frac{3}{8} + \frac{3}{10} = \frac{15 + 12}{40} = \frac{27}{40}$
