２分にぶんの１いち, ３分さんぶんの１いち, etc：How to Use Fractions in Japanese

What is the difference between “２に分ぶんの１いち(ni-bun-no-ichi) and ３さん分ぶんの１いち(san-bun-no-ichi)”? After reading this, you would be answering this question. Let me introduce what their subtle differences are and how you correctly use them such as native speakers today!

[wp-svg-icons icon=”checkmark-circle” wrap=”i”] 分数ぶんすう(bunsuu)

[wp-svg-icons icon=”arrow-right-2″ wrap=”span”] Fractions / 两分之一, 三分之一 / 2분의 1, 3분의 1 / Một nửa/ một phần hai, Một phần ba

“分数ぶんすう(bunsuu)” means “Fractions” and which have been used as the meaning of “a number that results from dividing one whole number by another”. The basic fractions are that ２に分ぶんの１いち(one-half), “３さん分ぶんの１いち(one-third)”, “３さん分ぶんの２に(two-thirds)”, “４よん分ぶんの３さん(three-fourths)”, “５ご分ぶんの４よん(four-fifths)”, “１００ひゃく分ぶんの１いt(one hundredth), etc. Everyone could use them as casual, polite and formal such as “地球ちきゅうの表面ひょうめんの４よん分ぶんの３さんは海うみだよ。(Three-fourths of the earth’s surface is water.)” as casual, and “地球ちきゅうの表面ひょうめんの４よん分ぶんの３さんは海うみです。(Three-fourths of the earth’s surface is water.)” as polite and formal. Furthermore, “plus” is “たす”, “minus” is “マイナス”, “multiplied by” is “かける” and “divided by” is “わる”.
