Questions & Answers about نسبت این رنگها شش واحد به یک واحد است.
How is the ratio structured in this sentence?
It uses the pattern [Numeral] + be + [Numeral]. Here, it is shesh vahed be yek vahed (six units to one unit). The preposition be translates to "to" and is the standard way to express proportions, odds, and sports scores in Farsi.
Do we have to repeat the word vahed (unit) for both numbers?
No, you can drop it just like in English. Saying shesh be yek (six to one) is perfectly natural and very common in everyday speech. Repeating vahed here just makes the statement sound a bit more formal or mathematically precise.
How does nesbat (ratio) connect to the phrase "these colors"?
They are connected by the unseen ezafe vowel, forming nesbat-e in rang-ha. This grammatical link acts just like the English preposition "of", literally translating to "the ratio of these colors".
Why does the sentence use in (this) instead of a plural word for "these" before rang-ha (colors)?
As a quick refresher, Farsi demonstrative adjectives like in (this/these) and ān (that/those) always stay singular when they come directly before a noun. The noun itself takes the plural suffix (-ha), which is entirely sufficient to show that we mean "these colors" rather than "this color".
