Thank you. I actually like your translation; at least it is better than what I thought myself. And I just found out the word for "score" - puntuacion. So I will try to use it in translating the second phrase.
>Literal, but not correct: Como le puede ganar un juego con el resultado de 7-0?
>
>>How would you translate the following phrase (question) to Spanish?:
>>
>>"How can you win a game with the score of 7-0?"
>>
>>And another phrase:
>>
>>"How do you score the game of tennis?"
>>
>>TIA
