Answer 2

The symbol * is replaced by the number 2.

Step-by-step explanation:

The symbol * can be replaced by the number 0 to 9 then we get,

2704 ÷ 3 = 901.33

2714 ÷ 3 = 904.66

2724 ÷ 3 = 908

2734 ÷ 3 = 911.33

2744 ÷ 3 = 914.66

2754 ÷ 3 = 918

2764 ÷ 3 = 921.33

2774 ÷ 3 = 924.66

2784 ÷ 3 = 928

2794 ÷ 3 = 931.33

The numbers 2724, 2754 and 2784 are divisible by 3.

From 2, 5 and 8, the number 2 is the smallest number.
