Setenta es más que sesenta.

Because Spanish uses más que to compare one thing directly with another:

• Setenta es más que sesenta. = Seventy is more than sixty.

Use más que when you are saying X is more than Y.

By contrast, más de is often used with:

• numbers/amounts: más de cien personas = more than a hundred people
• time/quantity expressions
• some other set phrases

So in a direct comparison between setenta and sesenta, más que is the normal choice.

Es is the third-person singular form of ser in the present tense.

• ser = to be
• es = is

So:

• Setenta es más que sesenta. literally follows the pattern:
• Seventy is more than sixty.

Even though setenta and sesenta are numbers, Spanish treats each number as a singular idea here, so es is singular.

Yes, but it is less natural in this basic numeric comparison.

For plain number comparisons, Spanish usually prefers:

• Setenta es más que sesenta.

Mayor que often means greater than or older than, and it can sound more formal or mathematical depending on context.

So:

• más que = the most common, everyday way here
• mayor que = possible, but not the usual beginner-friendly phrasing for simple numbers

The accent mark distinguishes más from mas.

• más = more
• mas = but (very formal/literary, not common in everyday speech)

So the accent is important because it changes the meaning.

In your sentence:

• más must have the accent because it means more

A simple Latin American-style pronunciation guide is:

• setenta ≈ seh-TEN-tah
• es ≈ ess
• más ≈ mahs
• que ≈ keh
• sesenta ≈ seh-SEN-tah

Put together:

• seh-TEN-tah ess mahs keh seh-SEN-tah

A few helpful points:

• s is normally a clear s sound
• t is a clean dental t, lighter than many English t sounds
• que sounds like keh, not like English kway

No. In this sentence, que is pronounced keh.

The u in que is normally silent, so:

• que = keh
• qui = kee

So:

• más que sounds like mahs keh

Not here.

In a simple statement comparing numbers, you normally just say:

• Setenta es más que sesenta.

Adding el would usually change the context, for example if you were talking about:

• a page number
• a year
• a score
• a specific number as a noun in a different way

For a basic numerical comparison, no article is needed.

For a normal, natural sentence, use:

• Setenta es más que sesenta.

Spanish can change word order for emphasis in some cases, but Más que sesenta es setenta sounds unnatural for this meaning.

So the safest pattern is:

• [number] + es + más que + [number]

Examples:

• Veinte es más que diez.
• Cien es más que noventa.

No, not in a complete sentence like this.

Spanish needs the verb:

• Setenta es más que sesenta.

Without es, it sounds incomplete or broken.

English also needs the verb here:

• Seventy is more than sixty.

So keep es.

No. As number words by themselves, they do not become plural in this kind of sentence.

You say:

• setenta
• sesenta

not:

• setentas
• sesentas

However, number words can sometimes act more like nouns in special contexts, but that is not what is happening here. In this sentence, they are just numbers being compared.

Spanish uses que after comparatives like más and menos to express what English often says with than.

So the structure is:

• más que = more than
• menos que = less than

Examples:

• Setenta es más que sesenta.
• Cinco es menos que diez.

So even though que often means that or which in other contexts, here it is part of the comparison pattern.

Yes, especially in a teaching, explanatory, or mathematical context.

For example:

• teaching numbers
• comparing quantities
• explaining basic math

In everyday life, a speaker might also phrase it more mathematically as:

• Setenta es mayor que sesenta.
• Setenta es más grande que sesenta is not natural for pure numbers

So your original sentence is understandable and natural enough, especially for learning and basic comparison.

Yes. This is a very useful pattern:

• [number] es más que [number]

Examples:

• Treinta es más que veinte.
• Cincuenta es más que cuarenta.
• Noventa es más que ochenta.

You can also use:

• [number] es menos que [number]

Examples:

• Sesenta es menos que setenta.
• Diez es menos que quince.

So this sentence is a good model for making many simple comparisons.
