1hl-1dal-1cl=?dl

Answer 1

$126~dal~=~\bold{1~260~l} \\ 3~hl~=~\bold{300~l} \\ 126~dal~+~3~hl~+~56~l~=~1~260~l~+~300~l~+56~l~=~\boxed{\bold{1~616~l}} \\ --------------------------- \\ 1~hl~=~\bold{1~000~dl} \\ 1~dal~=~\bold{100~dl} \\ 1~cl~=~\bold{0,1~dl} \\ 1~hl~-~1~dal~-~1~cl~=~1~000~dl~-~100~dl~-~0,1~dl~=~\boxed{\bold{899,9~dl}}$
