Fractions

Chapter – 7

Q 1. Write the fraction representing the shaded portion.

Ans: (i) 4 / 16

(ii) 3 / 16

(iii) 8 / 15

(iv) 6 / 8

Q 2. Write whether the fraction identifying the shaded portion is correct or not.

(i) 

Ans: Incorrect.

(ii)

Ans: Correct.

Q.3. Shade 7 parts of the adjacent ring. Write the fraction representing the shaded portion.

Ans: 7/16

Q.4. Write the natural numbers from 1 to 50. Encircle the prime numbers from them. What fraction of the natural numbers are prime numbers, express them.

Ans: The natural numbers from 1 to 50:

Total Numbers = 50

Total Prime numbers = 15

∴ 15/50 of the natural numbers are prime numbers.

Q. 5. What fraction of a year is 5 months.

Ans: 1 year = 12 months. 

∴ fraction of a year is 5 months = 5/12 

6. Write the proper fractions whose-

(a) Denominator is 11.

Ans: 7 /11

(b) Numerator is an even prime number and denominator is 3 more than that.

Ans: 5 / 2.

7. (a) Write a proper fraction whose, sum of denominator and numerator is 9. Is there any more proper fraction satisfying this condition? Match the fractions which you got, with the fractions, which your class – mate found out.

Ans: According to given condition, the proper fraction is 4/5. Such proper fraction are 1/3, 2 / 7,3 / 6,etc. 

(b) Write a proper fraction, whose numerator is 3 less than the denominator Can you write 5 more fractions of this type? Can you think, how many such fraction are there?

Ans: Five proper fraction and whose numeration is 3 less than the denominator are 1/4, 2/5, 3/6 ,4/7 and 5/8.

Those are many such fractions.

Q.8. Write a fraction whose numerator is 7 more than the denominator. Is it proper or improper fraction? Can you write 5 more fractions of this type?

Ans: 9 / 2[2 + 7 = 9], this is an improper fraction 

5 more fractions of this type are- 10 / 3, 11 / 4, 12 / 5, 13 / 6, 15 / 8.

Q.9. How can you share 5 apples among 3 students? Express the quantity received by each student in mixed fraction.

Ans: Out of 5 apples, 3 apples can be distributed among 3 students. The 4th and 5th apples can also be distributed among 3 students, thus each student receives (1 + ⅓ + 1 / 3) = (1 + 2 / 3) = 1 2 / 3  apples.

Q.10. How can you share 7 apples among 2 girls, (Use both the ways used earlier).

Ans: Let us suppose, 7 apples will be shared between 2 girls. Out of 7 apples, 6 apples are shared between 2 girls. The 7th apple is divided into two parts and shared by giving half of an apple to each of them.

Hence, the portion of the first girl is (3 + 1/2) of the apple 

and that of the second girl is (3 + 1/2) of the apple.

Again, this can be done by another other way also.

Ans: When 22 fruits are shared among persons, the each person gets 22/5 = 4 2/5 parts.

∴  Each person gets 4 whole fruits and ⅖ part.

8. Draw four circles of equal size. Show that 1/2, 2/4, 4/8 and 8/16 are equivalent fractions and that, they represent the same shared part of a whole and explain.

Q.2. Find three equivalent fractions of ⅜ (Can you represent them with the help

of pictures that they are equivalent)? 

Ans: 

Q. 3. Observe the adjoining figures. Write the fraction of the shaded parts in each of them. Are all these fraction equivalent?

Ans: (i) 15 / 25 = 3/5

∴ 15 x 5 = 75

25 x 3 = 75

(ii) 4 / 9 = 36 / 81

∴ 4 x 81 = 324

9 x 36 = 324

Q. 2. Fill in the—

(a) 

Ans:

(b) 

Ans: 

(c) 

Ans:

5. (a) Find the equivalent fractions of 5 / 8 having

(i) denominator 40

Ans: denominator = 40

(ii) denominator 6 more than the numerator.

Ans: Let the denominator be x + 6 

5/8 = x / x + 6

5(x + 6) = 8x

5x + 30 = 8x

30 = 8x – 5x

30=3x 

10 = x

the numerator is 10, and the denominator is: 10 + 6

= 16 

the required fraction is: 10 / 16.

(i) 45 / 60.

Ans: 45 / 60

45 = 3 x 3 x 5

60 = 2 x 2 x 3 x (5)

∴ H.C.F = 3 x 5 = 15.

(ii) 90/150

Ans: 90 / 150

90 = 2 x 3 x 3 x 5

150 = 2 x 3 x 5 x 5

∴ H.C.F = 2 x 3 x 5 = 30

(iii) 48/72

Ans: 48 / 72

48 = 2 × 2 × 2 × 2 × 3

72 = 2 × 2 × 2 × 3 × 3

Q.7. Priti and Riti’s mother kept the glass of milk on the table. She asked them to share the glass of milk. Priti took 2/4 parts of the milk and Riti took 1/2 part. How much milk was left in the glass?

Ans: Priti took milk from the glass full of milk = 2/4 part

 and Riti took milk = ½ Part. 

∵ Priti and Riti took milk together = 

∴ Amount of milk was left in the glass = 1-1 = 0

∴. No milk was left in the glass.

Nabamallika and 2/9 parts to Madhumalati.

Q.10. From a bucket full of water, 7/15 parts of water was used. How much water was left in the bucket?

Ans: From a bucket full of water, 7/15 parts of water was used.

Amount of water left in a bucket = (1 – 7 / 15)
