This term I have focused on adding and subtracting factions. I know that 1 fifth + 3 fifths = 4/5 because your adding part of the same whole and I know that 3/4 -2/4=1/4 because When subtracting fractions with the same denominator, you keep the bottom number that denominator the same and simply subtract the top numbers the numerators: 3 minus 2 equal 1 which gives you 1/4.
