Answer 1

Resposta:

2,03...

Explicação passo a passo:

$2-(\frac{1}{2} -\frac{3}{5} ).\frac{1}{3} = 2-(\frac{1}{2}.\frac{1}{3} - \frac{3}{5}.\frac{1}{3}) = 2-(\frac{1}{6} - \frac{3}{15})$

M.M.C entre 6, 15:

$6,15/2\\3, 15/3\\1, 5/5\\1,1\\\\mmc=2.3.5=30$

Então teremos:

$2-(\frac{5-6}{30}) = 2-(\frac{-1}{30}) = 2+\frac{1}{30} = \frac{61}{30} = 2,033...$
