Write the fractions. Are all these fractions equivalent?

(a)

(b)

a) We can find fraction in each figure by the formula

Dark part/ total parts

½, 2/4= 1/2, 3/6= 1/2, 4/8= ½

These all are equivalent

b)

We can find fraction in each figure by the formula

Dark part/ total part

4/12=1/3, 3/9= 1/3, 2/6= 1/3, 1/3, 6/15

These all are not equivalent

Write the fractions and pair up the equivalent fractions from each row.

To find an equivalent fraction, we may multiply/divide both the numerator and the denominator by the same number.

a) Here in this we have to multiply by 4, so the answer would be 8/28

b) Here in this we have to multiply by 2, so the answer would be 10/16 c) Here in this we have to multiply by 4, so the answer would be 12/20

d) Here in this we have to divide by 3, so the answer would be 15/20

e) Here in this we have to divide by 6, so the answer would be 3/4

Find the equivalent fraction of 3/5 having

12/20 |

b) |
To make numerator 9, we need to multiple both by 3 |
9/15 |

c) |
To make denominator 30, we need to multiple both by 6 |
18/30 |

Check whether the given fractions are equivalent:

(a)

(b)

(c)

a) for the first fraction 5/9, if multiply both (numerator and denominator) by 6, then we get 30/54

So 5/9 and 30/54 are equivalent fraction

b) for the first fraction 3/10, if multiply both (numerator and denominator) by 4, then we get 12/40 and if multiply both (numerator and denominator) by 5 then we get 15/50

So 5/9 and 12/50 are not equivalent fraction

c) All the number in both the fraction are prime numbers, so there is no chance of them being equivalent

Reduce the following fractions to simplest form:

(a)

(b)

(c)

(d)

(e)

To reduce the fraction to simplest form, we need to find the HCF of numerator and denominator

Let’ s takes an example of first one

2 |
48,60 |

2 |
24,30 |

3 |
12,15 |

4,5 |

a) |
HCF of 48 and 60 is 12, So dividing by 12 on both numerator and denominator |
4/5 |

b) |
HCF of 150 and 60 is 12, So dividing by 30 on both numerator and denominator |
5/2 |

c) |
HCF of 84 and 98 is 14, So dividing by 14 on both numerator and denominator |
6/7 |

d) |
HCF of 12 and 52 is 4, So dividing by 4 on both numerator and denominator |
3/13 |

e) |
HCF of 7 and 28 is 7, So dividing by 7 on both numerator and denominator |
1/4 |

Ramesh had 20 pencils, Sheela had 50 pencils and Jamaal had 80 pencils. After 4 months, Ramesh used up 10 pencils, Sheela used up 25 pencils and Jamaal used up 40 pencils. What fraction did each use up? Check if each has used up an equal fraction of her/his pencils?

Fraction of pencils used by Ramesh = Used pencil/Total pencil =10/20 =1/2

Fraction of pencils used by Sheela = Used pencil/Total pencil =25/50 =1/2

Fractions of pencils used by Jamaal = Used pencil/Total pencil =40/80 =1/2

Yes, they have all used up an equal fraction of his/her pencils.

Write shaded portion as fraction. Arrange them in ascending and descending order using correct sign ‘<’, ‘=’, ‘>’ between the fractions:

(a)

(b)

(c) Show 2/6, 4/6, 8/6, 6/6 on the number line. Put appropriate signs between the fractions given.

The fractions represented by the shaded portions are as follows:

b) 3/8, 4/9, 3/9, 6/9

When we compare two fraction

1) Like Fraction: if the denominator is same, the fraction with the greater numerator is greater.

2) Unlike Fraction: If the denominator is not same, we first get their equivalent fractions with a denominator which is the L.C.M of the denominators of both the fractions

The above fractions in a) and b) are like fractions as they have the same denominator.

When comparing fractions with same denominator,

So, arranging the fractions in ascending order, we have

a) 1/8 < 3/8 < 4/8 < 6/8

b) 3/9 < 4/9 < 6/9 < 8/9

c)Let us represent the fractions 2/6, 4/6, 8/6, 6/6 on the number line.

Again these comparisons are between the like fractions, so numerator will dictate the sign

Compare the fractions and put an appropriate sign.

Find answers to the following. Write and indicate how you solved them.

(a) Is 5/9 equal to 4/5?

(b) Is 9/16 equal to 5/9?

(c) Is 4/5 equal to 16/20?

(d) Is 1/15 equal to 4/30?

We need to first simplify each fraction. After simplication if they are equal, else it is not equal

a) Not equal

b) Not equal

c) equal

d) Not equal

Ila read 25 pages of a book containing 100 pages. Lalita read 2/5 of the same book. Who read less?

Total number of pages in the book = 100 pages

Number of pages read by Ila = 25 pages

Fraction of pages read by Ila = 25/100= 1/4

Lalita read 2/5 of the same book

So basically we need to compare the fraction ¼ and 2/5

Since they are unlike fraction, we need to find LCM of 4 and 5 which is 20

So ¼ = 5/20

2/5= 8/20

Now 8 > 5

So Ila read lesser than Lalita

Rafiq exercised for 3/6 of an hour, while Rohit exercised for ¾ of an hour. Who exercised for a longer time?

Rafiq =3/6

Rohit = ¾

We need to compare the fraction. Since these are unlike fraction, we need to calculate the LCM and 4 and 6. LCM of 4 and 6 is 12

Raft=3/6= 6/12

Rohit= ¾= 9/12

9/12 > 6/12

So clearly Rohit exercised more

In a class A of 25 students, 20 passed in first class; in another class B of 30 students, 24 passed in first class. In which class was a greater fraction of students getting first class?

Total number of students in class A = 25

Number of students passed in first class = 20.

Fraction of students of class A who passed in first class = 20/25=4/5

Total number of students in class B = 30

Number of students passed in first class = 24.

Fraction of students of class B who passed in first class =24/30 =4/5

Both class A and B have the same fraction of students who passed in first class.
