Answer:
11/20
Step-by-step explanation:
4/5 - 1/4 these have different denominators, to add or subtract two fractions of different denominators simply make their denominators the same. We do this by multiplying both numerator and denominator of each fraction by the other denominator:
4/5 * 4/4 = 16/20
1/4 * 5/5 = 5/20
4/5 - 1/4 = 16/20 - 5/20 = 11/20
