Question

a) ____is the smallest number that has to be subtracted from 425 to make the difference divisible by 3.​

Answer 1

Answer:

2

Step-by-step explanation:

423 is a multiple of 3

and it is 2 numbers away from 423

Therefore the answer is 2

Answer 2

Answer:

2 is the smallest number.

now

divisibility of 3 : the sum of digits should be divisible by 3.

now ,

sum of digits of 425 = 4+2+5= 11

11 is not divisible by 3. so we have to subtract a number so that the sum of digits becomes divisible by 3.

now,

the closest multiple of 3 is 9.so we have to subtract 2 from the number 425.

425-2= 423

sum of digits of 423 = 4+2+3= 9

the number 423 is divisible by 3.

hence, 2 should be subtracted from 425 to make the difference divisible by 3.
