Question

15/42-2 12/12=5x, 666x=66 1/66-95/33

Answer 1

$frac{15}{42}-2 frac{12}{12}=5 x$
$frac{15}{42}-3=5 x$
$frac{15}{42}- frac{126}{42} =5 x$
$- frac{111}{42}=5 x$
$x=- frac{111}{42*5}$
$x=- frac{111}{210}$

$666 x=66 frac{1}{66} - frac{95}{33}$
$666 x= frac{4257}{66} - frac{190}{66}$
$666 x= frac{4167}{66}$
$x= frac{4167}{66*666}$
$x= frac{4167}{43956}$
