Answer1) 5

2) 1.6

3) 522

4) 4375 metre

5) 25 minutes

6)15600 is the expenditure

3120 is his total savings

7) 750

8) 53.25

Step-by-step explanation:

Answer 1) 40÷8=5 is the answer

2) 4/11×22/5=1.6 is the answer

3) 3/4 of rupees 696 is 696÷4=174

174×3=522 is the answer

4) 5/8 of 7 km in metre is 7km=7000m÷8=875×5=4375m

5) 1 hour= 60 minutes so 60÷12=5×5=25 minutes is the answer

6)18720÷6=3120×5=15600 is the expenditure

18720-15600=3120 is his total savings

7) Let the total student be =1/1

students absent=1/25

students present=1/1-1/25=24/25

if 720 students were present on that day

then total number of students in school =

25/24×720=750.

8) The cost of 1 litre of milk=213/5

so cost of 25/2 litre of milk=?

-213/5x25/2=

53.25

Hence, the cost of 25/2 litre of milk is

53.25
