Learn Russian: Темп производства в пять раз выше, поэтому масштаб больше. - The pace of production is five times higher, therefore the scale is larger.

To express "X times [more/less/adjective]", Russian uses the preposition в + the number in the accusative case + the correct form of the word раз (time) + a comparative adjective. In this sentence, we have в + пять (for this number, the accusative form is identical to the nominative) + раз + выше (the comparative form of высокий, meaning "high").

Why is the word раз used after пять instead of a standard genitive plural ending like разов?

Numbers 5 and above require the noun that follows them to be in the genitive plural. The noun раз has an irregular, "zero-ending" genitive plural form: it stays exactly as раз. If the multiplier were 2, 3, or 4, you would use the genitive singular form раза instead (for example, в три раза выше).

Could I say более высокий instead of выше and более большой instead of больше here?

It would sound very unnatural. When the comparative acts as the main predicate of the sentence (meaning you are saying "the pace is higher" or "the scale is larger"), Russian strongly prefers the simple, one-word comparative forms (выше, больше). You would generally only use the compound forms (like более высокий) when attaching the adjective directly to a noun, such as "a higher pace" (более высокий темп).

What is the difference between and , and why is used in this sentence?
