Hi John, this sentence make no sense: "75 % de los niños que se inscribieron en la escuela primaria no contaba con los conocimientos básicos para determinados puestos de trabajo". Literally you are saying: 75% of children who enrolled to elementary school did not have basic knowledge for some jobs.

Maybe you wanted to say: 75 % de los niños que se inscribieron en la escuela primaria no contaba con los conocimientos básicos requeridos en el plan de estudios (75% of children who enrolled to elementary school did not have basic knowledge required by the curriculum).

In the sentence: "Para ayudar a este problema..." In spanish it means: to help to increase this problem. Perhaps, you wanted to say: "para contrarrestar este problema" (to counteract this problem).

Finally, I did not understand what did you want to say in this sentence:"Esto ayudó a la mano de obra mexicana para aumentar más de 49,000,00."
