- The predecessor 10000 is —————
- The natural number which has no predecessor is —————-
- For any whole numbers a, b and c, (a + b) + c = a + (b + c).This property is known as ——
- Tell which property is used here: 2 x 43 x 65 = 65 x 43 x 2.
**Answer the following:** - Write the predecessor and successor of

a) 1999

b) 12000 - The school canteen charges Rs 55 for lunch and Rs 26 for snacks. How much money do you spend in 6 days on these things?
- Find 24 x 102 using distributive property.
- Find 698 x 78 + 22 x 698 using distributive property.
- Find the product by suitable rearrangement: 4 x 675 x 25.

**ANSWERS:**

- 8976013.
- 9999
- 1
- Associativity of addition.
- Commutativity under addition
- a)Predecessor of 1999 is 1998 and successor of 1999 is 2000.

b) Predecessor of 12000 is 11999 and successor is 12001. - Cost of lunch = 6 x 55 =330

Cost of snacks = 6 x 26 = 156

Total cost = 330 + 156 = Rs 486. - 24 x 102 = 24 x (100 + 2) =24 x 100 + 24 x 2

= 2400 + 48

= 2448 - 698 x 78 + 22 x 698 = 698 x (78 + 22) = 698 x 100 = 69800.
- 4 x 675 x 25 = (4 x 25) x 675 = 100 x 675 = 67500.
