Answer 1

Hi Jesset, these answers look good. The only one I am noticing is wrong is #6. "Lentamente" is an adverb, so you wouldn't use "tanta" which is used quantitatively to modify a noun, but "tan."

Answer 2

Hi. I think for the most part, you agree in gender and number for your answers. However, if you checked a simple Spanish to English translation on Google, you would see how number 6 is incorrect. "Lentamente" is from the root word, "lento," meaning slow, so it becomes a singular and masculine designation: "Ellos caminan tan lentamente como vosotros."
