Question

A] Using divisibility rules determine the following. Give reasons for your answer 1. Is 4,38,750 divisible by 6? 2. Is 7,01,69,308 divisible by 11?

Answer 1

Answer:

1. yes

2. yes

Step-by-step explanation:

1. 4,38,750

rule for 6: no. should be multiple of 2 and 3 both

it is multiple of 2 as it is even

sum of numbers = 4+3+8+7+5+0 = 27 = multiple of 3

thus it is also a multiple of 6

2. 7,01,69,308

rule for 11: diff bw sum of digits at odd and even places should be multiple of 11 or 0.

sum of digits at odd place = 7+1+9+0 = 17

sum of digits at even place = 0+6+3+8 = 17

diff = 17-17 = 0

thus it is a multiple of 11
