Q4. Add

a) 3/4 + 5/3

Lcm of 4 and 3 =12

9/12 +20/12 = 29/12

b) 5/6 +4/3

Lcm = 3 and 6 = 6

5/6 +8/6 = 13/6

c) 2/3 +1/6

Lcm 0f 3 and 6 =6

4/6 +1/6 = 5/6

d) 7/2 - 8/5

Lcm 0f 2 and 5 = 10

35/10 - 16/10 = 19/10

e) 3/2 - 1/4

Lcm of 2 and 4 = 4

6/4 -1/4 = 5/4

f) 8/3 -2/5

Lcm of 3 and 5 = 15

40/15 - 6/15 = 34/15

Q5.a) 3/4 of 16

3/4 X16 =12

b) 2/3 0f 33 = 2/3 X33 = 22

in 7 th bus how many children will seat = 340-312 = 28 students

No. of empty seats = 52-28 = 24
