Question

1.) which natural number has no predecessor?
i) 1 ii) 2 iii) 0 iv) none of these.
2.) which is the smallest whole number?
i) 0 ii) 2 iii) 1 iv) none of these.
3.) study the patten:-
i) 1 × 8 + 1 = 9.
ii) 12 × 8 + 2 = 98
a) 120 × 8 + 3 = 963
b) none of these
c) 123 × 8 + 3 = 987
d) 1234 × 8 + 4 = 9876.
4.) 460____406
a) =
b) none of these
c) >
d) <
5.) Match the following :-
COLUMNS A = COLUMNS B
i) Commutative property = (a × b) × c = a = (b× c)
ii) Associative property = a (b +c) = ab + ac
iii) identify for multiplication = a + b = b + a
iv) Distributive property = a × 1 = a
​

Answer 1

Answer:

1) none of these

2) 0

3) a

4)≥

5)commutative property -- a+b=b+a

associative property ---(a*b)*c=a*(b*c)

identtity for multiplication---a*1=a
