Question 10: Find the sum:
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
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
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?
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?
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)
Question 13: Fill in the blanks:
Question 14: Ring the improper fractions:
