Question

DETERMINE O VALOR
a)3/2÷6/5+1/4. b)-5/4-5/9÷10/3​

Answer 1

Resposta:

$\frac{ \frac{3}{2} }{ \frac{6}{5} } + \frac{1}{4} \\ \frac{3}{2} + \frac{5}{6} + \frac{1}{4} \\ \frac{15}{12} + \frac{1}{4} = \frac{5}{4} + \frac{1}{4} = \frac{5 + 1}{4} = \frac{6}{4} = \frac{3}{2} = 1 \frac{1}{2}$

segue a mesma logica na letra b)

espero ter ajudado.
