right seven parts out of 8 in fraction
Answers
Answer: A fraction is a number representing a part of a whole. The whole may be a single object or a group of objects.
Consider the fraction 7/12. This fraction is read as ”seven-twelfth” which means that 7 parts out of 12 equal parts in which the whole is divided. In the fraction 7/12, 7 is called the numerator and 12 is called the denominator.
Following are some more fractions:
(i) The fraction 5/7 is read as ”five-seventh” which means that 5 parts out of 7 equal parts in which the whole is divided. In the fraction 5/7, 5 is called the numerator and 7 is called the denominator.
(ii) The fraction 3/10 is read as ”three-tenth” which means that 3 parts out of 10 equal parts in which the whole is divided. In the fraction 3/10, 3 is called the numerator and 10 is called the denominator.
(iii) The fraction 1/5 is read as ”one-fifth” which means that 1 parts out of 5 equal parts in which the whole is divided. In the fraction 1/5, 1 is called the numerator and 5 is called the denominator.
For example:
1. Mrs. Brown has 24 apples. She ate 1/4 of them.
(i) How many apples does she eat?
(ii) How many does she have left?
Solution:
(i) Here the fraction 1/4 means take 1 part from 4 equal parts.
So, arrange 24 apples in four equal groups.
Clearly, each group will contain 24 ÷ 4 = 6 apples.
Thus, 1/4 of 24 is 6.
Hence, Mrs. Brown ate 6 apples.
(ii) Number of left out apples = 24 – 6 = 18.
2. Andrea has a packet of 20 biscuits. She gives 1/2 of them to Andy and 1/4 of them to Sally. The rest she keeps.
(i) How many biscuits does Andy get?
(ii) How many biscuits does Sally get?
(iii) How many biscuits does Andrea keep?
Solution:
(i) Here, 1/2 of 20 means take 1 part from two equal parts.
So, we arrange 20 biscuits in two equal parts.
Clearly, each part will contain 20 ÷ 2 = 10 biscuits.
Therefore, 1/2 of 20 is 10.
Hence, Andy gets 10 biscuits.
(ii) 1/4 of 20 means take 1 part from four equal parts.
So, we arrange 20 biscuits in four equal parts.
Clearly, each part will contain 20 ÷ 4 = 5 biscuits.
Therefore, 1/4 of 20 is 5.
Hence, Sally gets 5 biscuits.
(iii) Clearly, left out biscuits are kept by Andrea.
Therefore, Andrea keeps 20 – 10 – 5 = 5 biscuits.
3. What fraction of a day is 8 hours?
Solution:
We have,
One day = 12 hours.
Therefore, 8 hours = 8/12 of a day.
Hence, 8 hours is 8/12 part of a day.
4. Determine 2/3 of a collection of 9 balls.
Solution:
In order to find 2/3 of a collection of 9 balls, we divide the collection of 9 balls in 3 equal parts and take 2 such parts. Clearly, each row has 9/3 = 3 balls.
When, we take 2 rows out of 3 rows. It represents 2/3 of 9 balls. There are 6 balls in 2 rows.
Hence, 2/3 of 9 balls = 6 balls.
answer
7 part out of 8 = 7/8
Step-by-step explanation:
for example take an one apple then cuts its four parts then one part eat...then the remaining 3/4
I hope u understand
