Find a common denominator for the three given fractions and add them. Subtract the sum of your fractions from 1. The result will be the fraction of the total time she spent on English. Knowing the time spent English and the fraction of the total time spent studying that was spent on English allows you to calculate the total time spent studying. Then the time spent on Spanish is 
of that total time.
