Question

EXERCISE 3.1
Check the divisibility of the following numbers by 3 and 9.
(a) 723
(b) 9,604
(c) 8,325
Check the divisibility of the following numbers by 5 and 10.
(d) 2,01,364​

Answer 1

Answer:

option (a) and (c) are divisible by 3 and (c) is divisible by 9

Step-by-step explanation:

the no. whose sum is the multilpe of 3 and 9 that no is divisible by 3 and 9

So,

a) . (7+2+3) = 12

so this no is only divisible by 3

b) . (9+6+0+4) = 19

So this no is not divisible by 9 or 3

c). (8+3+2+5) = 18

So tis no ia divisible by both 3 and 9 .

Divisibility by 5

the no having 0 and 5 at the end is divisible by 5 and 10

a) . 201364 is not divisible by 5 and 3

Answer 2

Answer:

as first (a) is by, 3(b) i

Step-by-step explanation:

(a)

(7+2+3)=12is divisible by 3

(b) (9+6+

0+4)=isn't divisible any thing

(c) (8+3+2+5)=18is divisible by both

(d)2,01,364 as per divisibility rule 5 and 10 is not divisible by both because the unit sessions are not has O (or) 5 so then it is not
