"Nelíbí se mi to číslo, které vidím na váze."

Translation: I do not like the number that I see on the scale.

I would say on the scales.

[dsarkarati]

"to" can mean "the" or "that", so "I don't like that number which I see on the scale" should be correct.

[svrsheque]

sounds quite rough here, but i added it.

"I don't like the number that I am seeing on the weighing scale" should be accepted, I think.
