Question

Jim was celebrating his birthday with his friends. He gave $3$ chocolates to each of his friends. If he distributed $18$ chocolates in total, calculate the number of friends Jim has.

• A. $4$
• B. $5$
• C. $6$
• D. $18$

Answer 1

The correct option is C $6$

The ratio of the number of chocolates to the number of friends is $3:1$.

Now, let's draw the double number line.

For $3$ chocolates, there is one friend.

The ratio $3:1$, which means that we have to add $3$ to the top line and $1$ to the bottom line.


From the double number line, we can see that for $18$ chocolates, there are $6$ friends.

Hence, Jim has $6$ friends.
