Pete looked at the colors of the shoes worn by his classmates. He found that 1/5 of the class wore white shoes, 3/20 wore blue shoes, 2/5 wore black shoes, and 1/4 wore red shoes. what color shoes did the most students have on? And how would i show the work? PLEASE HELP

We need to change all of these fractions to equivalent fractions with common denominators.
Multiply the numerator and the denominator by the same number to get a denominator of 20.
1/5 = 4/20
2/5 = 8/20
1/4 = 5/20
