Question

in 234*16 replace * by a smallest digit to make it divisible by 3​

Answer 1

Answer:

2 must replace *

Step-by-step explanation:

divisibility test for 3 is ⇒ sum of all the digits must be divisible by 3

here we have in 234*16

2+3+4+*+1+6= 16+*

therefore smallest number that would replace * must be 2

since 16+2 i.e. 18 is a multiple of 3 and is divisible by 3

therefore the number must be 234216

Answer 2

Answer:

to check divisibility of 3 we add all digits then divide by 3 if the sum is divisible then no. is divisible

solution:2+3+4+2+1+6=18/3=6

the smallest no.is 2
