。
She and her sister are completely different in every way.
Literal
She [topic-は] older-sister [from-とは] 1 [from-から] 10 [until-まで] differs.
Modern Japanese mixes Arabic numerals (1, 10) and kanji numerals (一, 十) freely. Kanji feels more traditional, ceremonial, or literary; Arabic numerals dominate casual writing, business, and contemporary fiction — the same idiom 一から十まで ('from one to ten,' i.e. 'in every respect, completely') can be written either way. The とは marks 姉 as the standard of comparison with extra topic emphasis. Without an explicit 性格 ('personality'), the sentence reads abstractly as 'differ in every way.'
