There are 63 students in a speech contest. yesterday 1/3 gave a speech and today 2/3 of the remaining students gave their speech. how many students still haven't given their speeches

Hey!

Solution:

Find 1/3 of 63.

63 / 3 = 21

21 students gave a speech today.

63 - 21 = 42

Find 2/3 of 42.

42 / 3 = 14

14 x 2 = 28

28 of the remaining students gave their speeches.

42 - 28 = 14

14 students haven't given their speeches!
