The requried solution for each percentage is
1. 350 is 70% of 500 2. 37.5% of 64 is 24
3. 40% of 6.50 is 2.60 4. 20 of 140 is 28.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
We have to determine a number, whose 70% is 350
Let eh number x,
According to the question,
70% of x = 350
x = 350/ 70%
x = 350/0.70
x = 500
Similarly,
37.5% of 64 is 24
40% of 6.50 is 2.60
20 of 140 is 28.
Thus, the requried solution for each percentage is shown above.

Answer:
7/39 = 17.94%
Step-by-step explanation:
Town Students Relative Frequency
Wilmette 12 boys + 7 girls = 19 19/39 = 48.72%
Glencoe 9 girls + 4 boys = 13 13/39 = 33.33%
Kenilworth 2 boys + 5 girls = 7 7/39 = 17.94%
Total 39 students 39/39 = 100%
Another approach to solve probability is the Relative Frequency. A frequency is the number of times an event occurs. To solve for the relative frequency, it’s the ratio of the frequency of an event to the total outcomes. From the question, it is clear that for each town, it was subdivided into boys and girls but the word students represent the combined number of boys and girls for a particular town. so finding the probability that a student called at random to answer a question is from kenilworth is simply the ratio of students from kenilworth over the total number of students in the class.
