explain but explain in a way I could write it or draw it on paper
make it easy

Answer 1

Answer: 24

Easy ways to show it on paper:

1) Grouping (draw this)
- Draw 24 dots:
••• ••• ••• ••• ••• ••• ••• •••
- Circle each group of 3 dots. You get 8 full groups and no leftovers, so 24 is a multiple of 3.
- If you try the same for 7 or 16 you’ll have leftovers (7 → two groups of 3 and 1 left; 16 → five groups of 3 and 1 left), so they are not multiples of 3.

2) Quick number trick (write this)
- A number is a multiple of 3 if the sum of its digits is a multiple of 3.
- For 24: 2 + 4 = 6, and 6 is divisible by 3 → so 24 is divisible by 3.
- For 16: 1 + 6 = 7 (not divisible by 3). For 7 and 2 their digits (7 and 2) are not multiples of 3.

Either way shows 24 is the multiple of 3.
