1) EVALUATE USING SUITABLE REARRANGEMENT ALSO MENTION THE PROPERTY OF WHOLE NUMBER USED.
a) 8 X 3754 X 125
ans: 3754x(125x8)
=3754x1000
=3754000
b) 453 X 2 X 50
ans: 453x(50x2)
=453x100
=45300
c) 637 + 463 + 608
ans: 608+(463+637)
=608+1100
=1708
d) 196 + 905 + 304 + 95
ans: (196+304)+(905+95)
=500+1000
=1500
-I am sorry, but I do not know the names of the properties, I only know how to do the properties.

2) Simplify using distributive property of multiplication:
a) 595 x 96 + 4 x 595
ans: 595x(96+4)
=595x100
=59500
b) 297 x 17 + 297 x 3
ans: 297x(17+3)
=297x20
=5940

3) Find the value using the properties:
a) 972 x 8 + 972 x 2
ans:972x(8+2)
=972x10
=9720
b) 46 x 982 + 54 x 14
ans:(46x982)+(54x14)
=45172+756
=45928
c) 143 x 314 - 143 x 14
ans:143x(314-14)
=143x300
=42900
d) 305 x 115 - 305 x 15
ans: 305x(115-15)
=305x100
=30500

4) A taxi driver filled his petrol tank with 40 litres of petrol on Monday. The next day he fled the tank with 50 litres of petrol. If the petrol costs Rs 83 per litre how he spend in all on petrol ?
ans: 1 litre of petrol=Rs 83
40 litres of petrol =83x40
=Rs3320
-the taxi driver payed Rs3320 on monday.
_____________________________
1 litre of petrol=Rs 83
50 litres of petrol =83x50
=Rs4150
-the taxi driver payed Rs4150 on the next day.
_____________________________
total amount of money= Rs3320+Rs4150
=Rs7470
-the taxi driver payed Rs7470 totally.

5) 25 sets each containing a pencil and ruler each is made. The cost of each pencil is Dhs 2 and that of ruler is Dhs 8. What is the cost of 25 sets? Solve using property.
ans: amount of 1 pencil=2 dhs
amount of 1 scale=8 dhs
total amount of 1 set=2 dhs+8 dhs
= 10 dhs
total amount of 25 sets=25x(2+8)
=25x10
=250 dhs
