-
Not multiples of 2: 13, 25, 37, 49
Explanation:
-
10: Ends in 0 → Multiple of 2.
-
12: Ends in 2 → Multiple of 2.
-
14: Ends in 4 → Multiple of 2.
-
26: Ends in 6 → Multiple of 2.
-
13: Ends in 3 → Not a multiple of 2.
-
25: Ends in 5 → Not a multiple of 2.
-
37: Ends in 7 → Not a multiple of 2.
-
49: Ends in 9 → Not a multiple of 2.
####
Step 2: Multiples of 10
-
Rule: A number is a multiple of 10 if it ends in 0.
-
Given Examples:
-
Multiples of 10: 10, 30, 40, 50
-
Not multiples of 10: 16, 28, 34, 45
Explanation:
-
10: Ends in 0 → Multiple of 10.
-
30: Ends in 0 → Multiple of 10.
-
40: Ends in 0 → Multiple of 10.
-
50: Ends in 0 → Multiple of 10.
-
16: Ends in 6 → Not a multiple of 10.
-
28: Ends in 8 → Not a multiple of 10.
-
34: Ends in 4 → Not a multiple of 10.
-
45: Ends in 5 → Not a multiple of 10.
####
Step 3: Multiples of 5
-
Rule: A number is a multiple of 5 if it ends in 5 or 0.
-
Given Examples:
-
Multiples of 5: 15, 20, 45, 70
-
Not multiples of 5: 18, 24, 39, 56
Explanation:
-
15: Ends in 5 → Multiple of 5.
-
20: Ends in 0 → Multiple of 5.
-
45: Ends in 5 → Multiple of 5.
-
70: Ends in 0 → Multiple of 5.
-
18: Ends in 8 → Not a multiple of 5.
-
24: Ends in 4 → Not a multiple of 5.
-
39: Ends in 9 → Not a multiple of 5.
