Answer:
Fraction: 1/3 Number: 78 hope this helps ;)
Step-by-step:
Fraction: So, we see that 2/3 of the people returned their permission slip and the number of people who haven't would be 1/3 because 1 - 2/3 = 1/3
Number: So, first we see that there is 234 students and 2/3 of the students have returned their permission slip, so we would take 2/3 of 234 which would be 2/3 x 234 = 78
