Percent Problem?

Question

Favorite Snacks of the students

Boiled Banana - 34 students favorite snack
Bread - 79 students favorite snack
Cookies - 47 students favorite snack
Fruits - 40 students favorite snack


What percent of the students chose boiled banana as their favorite snack?

Answer 1

Ok.

First find the total number of students:

34+79+47+40=200

So the percentage of students who prefer boiled banana=

(34/200)*100=17%

I hope that is of some assistance.

Answer 2

The term percent means "per": as part of
and "cent" : french word for 100,
thus percent or part of 100.

Now on to the problem:
Add up all of the students: 34+79+47+40= 200
Now since 34 is the number in which we are interested, we find that this (and this is what a fraction means) is 34/200 of the entire student body. To turn this into a percent we use the division given that is 34 divided by 200 (again this is what the fraction means). And
34 divided by 200 is .17 (which means 17 hundreths and since we are now talking about hundreths we are talking about percent ,thus 17 percent.

Answer 3

34 + 79 + 47 + 40 = 200 [the summation of all the students]

... 34/200 = .17 [the ratio between the likeness of boiled bananas amongst all the students]

... .17(100) = 17% ... the percentage of the students who chose boiled banana as their favorite snack.

Answer 4

All the answers you have been given are right. The thing to remember is that 'per cent' simply means 'per hundred'. So, with a nice round number (like 200 students), then the easy way to get the percentage is to divide any the students' numbers by the fraction of the total that 100 is. In this case, 100 is half of 200 so you divide their totals by two:

Banana 34/2 = 17%
Bread 79/2 = 39.5%
Cookies 47/2 = 23.5%
Fruits 40/2 = 20%
-----------------------------
Total 100%

Okay? It's really very simple. Just find the factor of the total number of whatever objects/people in relation to one hundred and you then can calculate the percentage. Easy, really.

If you had a different problem with only (say) fifty students, then you'd double the number for each group of students to get the percentage, because 100 is two times 50.

Like: there are fifty students. Ten of them study German, eight study French, nineteen study Spanish, and thirteen study Greek.

Percentages?

German 10 x 2 = 20%
French 8 x 2 = 16%
Spanish 19 x 2 = 38%
Greek 13 x 2 = 26%
------------------------------
Total 100%

Hope this helps.

Answer 5

No clue has been given as to the total number of students. The plain assumption would be to assume the four categories of snacks and corresponding number of students to be mutually exclusive. In that case, the percent of students who chose boiled banana as their favorite snack would be:
(34/34+79+47+40) X 100 = 17 per cent.
However, one can also assume that the total number of students was 79, the highest number for bread. In that case the percent of choices would be as followsI
Boiled banana: (34X100)/79 = 43.04%
Bread: (79X100)/79= 100%
Cookies: (47X100)/79= 59.49%
Fruits: (40X100)/79=50.63%
Interpretation of results: All students liked bread; around half of them liked fruits; around six out of ten liked cookies; and around four out of ten liked boiled banana.

Answer 6

34 + 79 + 47 + 40 = 100%
200 students = 100%
So,
(34 x 100) : 200 = 17%
(79 x 100) : 200 = 39,5%
(47 x 100) : 200 = 23,5%
(40 x 100) : 200 = 20%
(34 + 79 + 47 + 40)students = (17+39,5+23,5+20)%
200 students = 100%

Answer 7

17 percent. Add the total number of students together, then divide that number into 34, the number of students who like banana, and multiply the result x 100.

Answer 8

% = 34 / (34+79+47+40) = 0.17 = 17%

Answer 9

34x+79x+47x+40x=200x
boiled banana=(34x/200x)*100
34/2
=17%
