Example Question #1 : Whole And Part
There are 24 slices of bread in a loaf of bread. If Karl eats of the loaf of bread, how many slices of bread has he eaten?
Karl has eaten 1 part out of a possible 3 parts of the loaf of bread. To find out how big each part is, we divide 24 by the number of parts (3).
So each part would be 8 slices of bread. Karl ate 1 part, so he has eaten 8 slices of bread.
Example Question #2 : Whole And Part
What is 62% of 23? Round to the nearest tenths place.
14.26
14.2
13.4
14.3
14.3
To find the part from the whole, you will need to multiply the whole (23) by the percent. In order to do this, first change the percent to a decimal (62% becomes 0.62).
The question askes you to round to the nearest tenths place: 14.26 becomes 14.3.
Therefore, 62% of 23 is 14.3.
Example Question #643 : Isee Lower Level (Grades 5 6) Quantitative Reasoning
If the probability of Ms. Jones calling on a male student during class is , and there are students in the class, how many students are female?
9
There are students in Ms. Jones' class. Since the probability of her calling on a male student is , we must first find of .
Now we must reduce by dividing both the top and bottom by .
is the same as , so there are male students in Ms. Jones' class. In order to find the number of female students in Ms. Jones' class, we must subtract from the total number of students in the class, which is .
There are female students in Ms. Jones' class.
Example Question #1 : How To Find The Part From The Whole
Find % of of .
First, we need to find of . Multiply to get .
Then, we need to find of . Multiply to get .
Example Question #3 : Whole And Part
Which of the following numbers is NOT a prime factor of ?
All of the answer choices are factors of seventy, but only one is not prime.
A prime number is a number greater than one that has only one and itself as divisors.
Thirty-five is not a prime number, because in addition to being divisible by one and itself, it is also divisible by five and seven. Therefore, the answer is thirty-five.
Example Question #4 : Whole And Part
Twenty students voted on their favorite sports. Eight students voted for tennis, four voted for basketball, and two voted for swimming. What fraction of the students voted for other sports?
To solve this problem, begin by finding the total number of students that voted for tennis, basketball, or swimming.
We are told there are twenty students in the class, and now we know that fourteen of those twenty voted for the three sports mentioned. The remaining students voted for other sports.
Six out of the twenty students, or of the class, voted for other sports.
When we reduce to simplest form (divide the numerator and denominator by two), we get the fraction .
Therefore, of the students voted for other sports.
