Hay aproximadamente (110,000,000) de personas en méxico. ciento diez millones ciento diez mil once millones ciento diez billones

Hay aproximadamente (110,000,000) de personas en México translates to "There are approximately one hundred ten million people in Mexico" (which I don't think is accurate information today). The options are as follows.

Let's break down that large number. The first part of it is "one hundred" which is cien in Spanish; in this scenario, it would be take the form ciento. That eliminates one of the options (once millones). The next part is "ten" which is diez in Spanish; this doesn't narrow the options down any further... The third part is "million" which (in plural form) is millones in Spanish.

Hay aproximadamente ciento diez millones de personas en México

ciento diez millones

ciento diez mil - 110,000 (mil means thousand; plural form is miles)
once millones - 11,000,000
ciento diez billones - 110,000,000,000 (billones is "billions" in Spanish; this answer is far more people than there are in the world - certainly not the population of Mexico alone!)
