Давайте разделим торт поровну.

Давайте is a very common way to say let’s in Russian.

So Давайте разделим торт поровну is basically Let’s divide the cake equally.

A useful pattern is:

• давайте + 1st person plural verb
• давайте + infinitive

Examples:

• Давайте пойдём. = Let’s go.
• Давайте читать. = Let’s read.

In your sentence, давайте makes the whole sentence into a suggestion or invitation to do something together.

Разделим is the 1st person plural form of the verb разделить. Literally, it means we will divide, but after давайте it functions like let’s divide.

This is normal in Russian. Instead of using a special imperative form for we, Russian often uses:

• давайте + 1st person plural verb

So:

• Давайте разделим = Let’s divide

This is one of the standard ways to make a suggestion involving the speaker and other people.

It comes from the verb разделить, which means to divide, to split, or to share out.

Here is the basic breakdown:

• infinitive: разделить
• 1st person plural future: мы разделим = we will divide
• in this sentence: давайте разделим = let’s divide

Because разделить is a perfective verb, разделим refers to a completed action: dividing the cake up.

Russian uses aspect very strongly.

• разделить = perfective, focusing on the result/completion
• делить = imperfective, focusing on process, repetition, or general activity

In this sentence, the idea is to divide the cake up as a single completed action, so разделить is the natural choice.

You are not talking about the general process of dividing cakes in life. You mean this specific cake, right now, into equal parts.

That is why разделим sounds right.

Yes, you could, but it sounds different.

• Давайте разделим торт поровну = Let’s divide the cake equally.
  Focus: one complete action, getting the cake divided.

• Давайте делить торт поровну = Let’s divide/share the cake equally.
  Focus: more on the process, or on the idea of dividing.

In many everyday situations, the perfective разделим is more natural because the goal is the finished result.

Because it is the direct object of the verb разделим.

The noun торт is masculine and inanimate. For masculine inanimate nouns, the accusative singular looks the same as the nominative singular.

So:

• nominative: торт
• accusative: торт

That is why you see торт and not a different ending.

Поровну means equally, into equal parts, or fairly evenly.

It is an adverb, and in this sentence it tells you how the cake should be divided.

So:

• разделим торт = let’s divide the cake
• разделим торт поровну = let’s divide the cake equally

You can also use поровну in other situations, for example:

• Поделим деньги поровну. = Let’s split the money equally.
• Они разделили работу поровну. = They divided the work equally.

Often both can mean divide or split, and in many contexts they are close.

For sharing something among people, Russian speakers very often use поделить or разделить. In this sentence, разделим sounds completely natural.

Very roughly:

• разделить can mean divide/split in a broad sense
• поделить often feels especially natural for sharing something out among people

So you might also hear:

• Давайте поделим торт поровну.

That would also be natural.

Not necessarily.

The form давайте historically contains the plural/formal ending -те, but as a fixed expression meaning let’s, it is used very widely and naturally in everyday speech.

It does not automatically make the sentence especially formal.

Compare:

• Давай разделим торт поровну. = Let’s divide the cake equally.
  More informal, usually to one friend or someone you address with ты.

• Давайте разделим торт поровну. = Let’s divide the cake equally.
  Can be used to several people, or politely, or just as a neutral standard let’s form.

Both can suggest the same action, but the tone is a little different.

• Давайте разделим торт поровну.
  A clear suggestion: Let’s divide the cake equally.

• Разделим торт поровну?
  More like: Shall we divide the cake equally?

Without давайте, the sentence can sound a bit lighter, more tentative, or more dependent on intonation and punctuation.

So давайте makes the suggestion more explicit.

Yes. Russian word order is flexible, though some orders sound more neutral than others.

The most neutral order here is:

• Давайте разделим торт поровну.

But you might also hear:

• Давайте торт разделим поровну.
• Торт давайте разделим поровну.

Changing the order can shift emphasis:

• putting торт earlier can emphasize the cake
• putting поровну later is very natural because it gives the important final detail: equally

For learners, the original sentence is the safest and most neutral version.

A helpful stress pattern is:

Дава́йте разделе́м торт поро́вну.

More carefully:

• дава́йте
• раздели́м or more standardly раздели́м? Actually the correct stress is раздели́м?
  In this form, the correct stress is раздели́м.
• торт
• поро́вну

So the full sentence is:

Дава́йте раздели́м торт поро́вну.

A rough English-style approximation might be:

da-VAI-tye raz-dye-LEEM tort pa-ROV-nu

But it is best to learn it from audio if possible, especially the soft consonants.

Not always exactly 50/50, but it usually means in equal shares.

The exact meaning depends on how many people are involved:

• two people: half and half
• three people: three equal parts
• four people: four equal parts

So in this sentence, поровну means the cake should be split into equal portions for whoever is sharing it.

Yes, absolutely. It sounds natural and idiomatic.

It is a very normal kind of Russian sentence:

• давайте for let’s
• a perfective verb for a single completed action
• поровну for equally

It is the kind of thing someone might say at a table, at a party, or when deciding how to share food fairly.
