Question

resuelve y ordena de menor a mayor 7/12-3/12+1/12=;1+1/4=;5×(2/9+1/3)-2/9=;(1+3/5)+1-2/3)=

Answer 1

$\frac{7}{12} - \frac{3}{12}+ \frac{1}{12} = \frac{7-3+1}{12} = \frac{5}{12} \\ \\ 1+ \frac{1}{4} =\frac{4}{4}+\frac{1}{4}=\frac{4+1}{4}=\frac{5}{4} \\ \\ 5*( \frac{2}{9} + \frac{1}{3} )- \frac{2}{9} =5*( \frac{2}{9} + \frac{3}{9} )- \frac{2}{9}=5* \frac{2+3}{9}- \frac{2}{9} =\frac{5*(2+3)-2 }{9} =\frac{23}{9} \\ \\ \frac{1+3}{5} +1- \frac{2}{3} = \frac{4}{5} +1- \frac{2}{3}= \frac{12}{15} + \frac{15}{15} - \frac{10}{15} = \frac{12+15-1}{15} = \frac{17}{15}$

Aproximadamente (con calculadora)

$\frac{5}{12}=0,416.. \\ \\ \frac{5}{4} =1,25 \\ \\ \frac{23}{9}=2,55... \\ \\ \frac{17}{15}=1,133... \\ \\ Luego, de menor a mayor \\ \\ \frac{5}{12};\frac{5}{4};\frac{17}{15};\frac{23}{9}$
