Question

replace * by the smallest digit so that (1) 392 * 52 * is divisible by 2 (2) 56 * 2 is divisible by 3​

Answer 1

Answer:

2 is the answer

Step-by-step explanation:

as mentioned in the question it should be the smallest digit. The divisibility rule of 2 is the number should be even. So if it is 2 3922522 would be the number and is even, hence divisible by 2. Likewise, in the second question the divisibility rule of 3 is that the sum of all the numbers should be divisible by 3. So if * is replaced by 2 the number would be 5622,

5+6+2+2= 15

15 is divisible by 3.

So 2 is the smallest digit that can replace *.
