Question

Resuelve las siguientes operaciones
a) 3/2+1/3+2/3+1/2
b) 2/3+1/4-1/2-3/4
c) 3/5×1/2÷2/3
d) 1/2+3/4-1/3×1/4+2/3÷1/3

Answer 1

a) $\frac{3}{2} + \frac{1}{3} + \frac{2}{3} + \frac{1}{2} = \frac{9+2+4+3}{6} = \frac{18}{6} = 3$

b) $\frac{2}{3} + \frac{1}{4} - \frac{1}{2} - \frac{3}{4} = \frac{8+3-6-9}{12} = \frac{-4}{12} =- \frac{1}{3}$

c) $\frac{3}{5} * \frac{1}{2} : \frac{2}{3} = \frac{3}{5} * \frac{4}{3} = \frac{12}{15}$

d) $\frac{1}{2} + \frac{3}{4} - \frac{1}{3} * \frac{1}{4} + \frac{2}{3} : \frac{1}{3} = \frac{1}{2} + \frac{3}{4} - \frac{1}{3} * \frac{1}{4} + \frac{3}{6} \\ \\ \frac{1}{2} + \frac{3}{4} - \frac{1}{12} + \frac{3}{6}= \frac{6+9-1+6}{12} = \frac{20}{12} = \frac{5}{3}$
