In a classroom of 28 students, 75% of the students have met their reading goal.
Label the double number line. How many students met their reading goal? What
fraction of 28 students met their reading goal? Explain.
Students
28
100%
Percent

21 students; 3/4 ; Possible explanation: 75% corresponds to 21 students.

So, 21 students met their reading goal. The fraction 75/100 represents 75%.

Therefore, 75/100, or 3/4, of 28 students met their reading goal.

Step-by-step explanation:

Number of students who met their reading goal = 75% of 28

Fraction: 21 students out of 28 met their reading goal

so,

3/4students met their reading goal

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
