Thank you for the opportunity to help you with your question!

total number of students=60

yesterday 1/3 of them gave their speech= 1/3 of 60= 20

subtracting 60-20= 40

today 1/4 of 40 gave their speech= 10

subtracting 40-10=30

the number of students who haven't given their speech is 30.

Please let me know if you need any clarification. I'm always happy to answer your questions.
