Question

1. Apply only divisibility rule and not the actual division method for the following: (172 +172)
a) Test the divisibility of the following number by 3: (i) 70335 (ii) 607439 (iii) 9082976
b) Test the divisibility of the following number by 11: (i) 5335 (ii) 70169803 (iii) 10000001​

Answer 1

Answer:

divisibility by 3

(i) 70335 = 7+0+3+3+5 = 18

Yes, it is divisible by 3 hence the 18 is multiple of 3.

(ii) 607439 = 6+0+7+4+3+9 = 29

No, it is not divisible by 3 hence 29 is not a multiple of 3 .
