    Hi uma

    To find the percentage of the students that get distinction :

    \text{ \% student} = \frac{\text{number of students that get distinction}}{\text{total student}} \, 100

    Now you can compute the percentages for math and english then compare them

    First, don't you mean 70 students out of 100, not .70 students? Going on that assumption, let's make them fractions and reduce:

    70/100 = 7/10 (reduce numerator and denominator by factor of 10) = 0.7
    80/120 = 8/12 = 4(2)/4(3) = 2/3 = 0.6 repeating or 0.67 rounded

    I think it's clear that . is a full stop to end the previous sentence.
