Question

(5/7 +55/77 +555/777) :5/7 - 111/500:(1/5+1/50+1/500) =

Answer 1

$(\frac{5}{7} + \frac{55}{77} +\frac{555}{777}):\frac{5}{7} -\frac{111}{500} :(\frac{1}{5} + \frac{1}{50} +\frac{1}{500})$

$= (\frac{5}{7} + \frac{5}{7} +\frac{5}{7}):\frac{5}{7} -\frac{111}{500} :[\frac{1}{5}*(1 + \frac{1}{10} +\frac{1}{100})]$

$=\frac{15}{7}*\frac{7}{5} -\frac{111}{500} :(\frac{1}{5}*\frac{100+10+1}{100} )$

$=\frac{15}{7}*\frac{7}{5} -\frac{111}{500} :(\frac{1}{5}*\frac{111}{100} )$

$=3-\frac{111}{500} :\frac{111}{500}$

$=3-\frac{111}{500} *\frac{500}{111}$

$=3-1$

$=2$
