Question

Explicación por favor:(

Answer 1

a)
$1+ \frac{2}{3} + \frac{3}{2} = \frac{1}{1} + \frac{2}{3} + \frac{3}{2}= \frac{(1*3*2)+(2*1*2)+(3*1*3)}{1*3*2} = \\ \\ = \frac{6+4+9}{6}= \frac{19}{6}$

c)
$\frac{1}{2} * \frac{3}{2} * \frac{4}{5} = \frac{(1*3*4)}{2*2*5} = \frac{12}{20} = \frac{3}{5}$

d)
$\frac{3}{4} : \frac{1}{2} - \frac{3}{2} : \frac{2}{5}= \frac{3*2}{4*1} - \frac{3*5}{2*2} = \frac{6}{4} - \frac{15}{4} =- \frac{9}{4}$
