"My mom is younger than yours."

Translation: Mi mamá es más joven que la tuya.

[Gato_fresca]

Why is the "la" needed here?

[doublelingot]

mine is el mío or la mía, and yours is el tuyo or la tuya

[vjamieson]

Wow, didn't know that. I could have sworn I remember lessons of La falda is mia, and such. I will try to remember this rule.

[Jonathan691496]

Always?

[JaJsemAdam]

When you say things like "it's mine" (es mío), there's no article, otherwise it's always there.

[Ralph37]

What a weird thing to compare.

[Corentin.FR]

Why "Mi mamá es más joven que las suyas" is not correct ?

[Chericher]

What's wrong with, "mi mamá es menor que la tuya"?

[Jonathan691496]

I think that means she is less than your mom which is mean

[dejoyf]

Why wrong? Mi madre es mas joven como de tuyo

[Amanda568957]

I think there are a few things here: tuyo should be tuya instead, since madre is feminine. "Mas" always goes with"que" in these "mas ____ que" phrases. Como would go with tan (mi madre es tan joven como la primavera - my mother is as young as the springtime). And the "de" isn't necessary because the "que" already covers the comparison. It's redundant in this case.

[olgaz007]

Also it should be "la tuya" instead of just "tuya", because we avoid repeating the same word (mamá) twice. See also https://www.duolingo.com/skill/es/Description-3/tips

You are a very good teacher!

[Chericher]

Madre means mother. Mamá means mom.

[AshokGanap]

El tuyo why is it wrong. Why dies it have to be la tuya

[jlseymour3]

Mamá is feminine, therefore la tuya.
