How do you specify percentages of verbs/actions?


I've been googling around a bit for an answer and I can't seem to find anyone
else asking this question. Apologies in advance if I'm wrong.

In English, you can say 'I do around 70% of the cooking'. How would you say
that in Japanese? Are non-する verbs like 'I do 30% of the carrying of boxes'
different?




I guess it depends on the nature of actions or just contexts, but structures
like _ActionのX%/X割はSubjがVerb_ or _ActionはX%/X割SubjがVerb_ can be broadly used.

Another thing is that it sounds more natural when actions are more concrete
tasks/objects, instead of just cooking or carrying.

Some examples (with possibly non-idiomatic translations)

  * 家事の7割は私がやっている _I do 70% of the household chores_
  * 食事の準備は７割がた私がやっている _As for preparation of meals, about 70% of the time I do it._
  * (引っ越しの時)荷物の８割は彼が運んだ _(When moving a house) he carried 80% of cardboard boxes_
