Question 5: Find the equivalent fraction of 64/84 with:

1. Denominator 63
   64/84 in lowest terms is,64/84 = 16/21
   21*3 = 63(63 is the new denominator )
   So 16 should be also multiplied by 3
   = 16/21*3/3 = 48/63
2. Denominator 147
   64/84 in lowest terms is,64/84=16/21
   16/21 x 3 = 112/147
3. Numerator 16
   64/84 in lowest terms is,
   64/84=16/21

Q6:  Subtract 2$\frac{2}{3}$ from 5, we get?

Q8: Which is smaller in each of the following pairs of fractions?

1. 3/16, 21/32
   Make the fractions equal
   3/16 x 2 = 6/32
   Thus, 3/16 is smaller.
2. 2/5, 7/12
   Make the fractions equal2/5 x 12 = 24/60
   7/12 x 5 = 35/60
   Thus, 2/5 is smaller.
3. 10/33, 1/3
   Make the fractions equal1/3 x 11 = 11/33
   Thus, 10/33 is smaller.

Q 9: Add together:

1. = 13/15
2. = 15/22
3. = 31/30

Question 10: Find the sum:

1. 
   Converting the mixed fractions into improper fractions 
   9/5 + 49/15 + 53/10 
   Now, making the denominator equal by LCM. 
   LCM = 30 
   9/5 x 6 = 54/30 
   49/15 x 2 = 98/30 
   53/10 x 3 = 159/30 
   Now the fractions are equal, adding them we get 
   54 + 98 + 159/30 =311/30 = 10(11/30)
2. 
   Converting the mixed fractions into improper fractions 

   3/5 + 36/7 + 11/2 

   Now, making the denominator equal by LCM. 

   LCM = 70 

   3/5 x 14 = 42/70

   36/7 x 10 = 360/70

   11/2 x 35 = 385/70

   Now the fractions are equal, adding them we get 

   42/70 + 360/70 +  385/70 = 787/70

3. 
   Converting the mixed fractions into improper fractions 

   19/8 + 29/16 + 3/4 

   Now, making the denominator equal by LCM. 

   LCM = 16 

   19/8 x 2 = 38/16

   3/4 x 4 = 12/16 

   Now the fractions are equal, adding them we get 

   38/16 + 13/16 + 12/16 = 63/16

4. 
   Converting the mixed fractions into improper fractions 

   12/9 + 2/24 + 7/36 

   Now, making the denominator equal by LCM. 

   LCM = 72 

   12/9 x 8 = 96/72

   2/24 x 3 = 6/72

   7/36 x 2 = 14/72 

   Now the fractions are equal, adding them we get 

   96/72 + 6/72 + 14/72 = 113/72

Question 11: Mukesh bought a pencil for Rs 2(1/4) and a sharpener for Rs 1(1/2). How much money did he spend on both these items?

Ans: Mukesh bought a pencil for = Rs 2(1/4)

Mukesh bought a sharpener for = Rs 1(1/2). 

Total money spent =  2(1/4) + 1(1/2). 

Converting the mixed fractions into improper fractions 

9/4 + 3/2 

LCM = 4     

3/2 x 2 = 6/4 

9/4 + 6/4 = Rs. 15/4

Question 12: Pankaj bought 5(1/9) litres of petrol on Monday, 2(5/6) litres on Tuesday and 1(2/9) litres on Wednesday. How many litres of petrol did he buy on these three days?

Ans: Pankaj bought petrol on Monday = 5(1/9) litres 

Pankaj bought petrol on Tuesday = 2(5/6) litres

Pankaj bought petrol on Wednesday = 1(2/9)litres

Total petrol on three days = 5(1/9) + 2(5/6) + 1(2/9)

Converting the mixed fractions into improper fractions 

46/9 + 15/6 + 11/9 

LCM = 18 

46/9 x 2 = 92/18 

15/6 x 3 = 45/18

11/9 x 2 = 22/18 

Adding them we get total petrol on three days = 159/18 = 8(5/6)

Q13: Fill in the blanks:

1. 1.
2. 2/11 x 11/2 = 1.
3. 17/3 x 3/17 = 1.

Q14: Ring the improper fractions:

Q15: 
is same as. Is it true?

Yes, , because we interchange the denominator and numerator when we change the sign.
