To solve this problem, we need to
place the blue dot at the correct position on the number line corresponding to the fraction:
$$
\frac{15}{7}
$$
---
Step 1: Convert the fraction to a mixed number
We divide 15 by 7:
$$
15 \div 7 = 2 \text{ remainder } 1
$$
So,
$$
\frac{15}{7} = 2 \frac{1}{7}
$$
This means the value is
2 and 1/7, which is
slightly more than 2, but less than 3.

Step 2: Understand the number line
The number line shows:
- Markings from 1 to 4.
- Between each whole number (e.g., between 2 and 3), there are
7 small ticks.
That means each tick represents
1/7 of a unit.
So:
- The first tick after 2 is $ 2 + \frac{1}{7} $
- The second tick is $ 2 + \frac{2}{7} $
- ...
- The seventh tick is $ 2 + \frac{7}{7} = 3 $
---
Step 3: Find where $ 2 \frac{1}{7} $ is
Since $ \frac{15}{7} = 2 \frac{1}{7} $, we want to place the dot at the
first tick after 2.
---
✔ Final Answer:
Drag the blue dot to the
first tick mark to the right of 2 on the number line.
This corresponds to $ 2 + \frac{1}{7} = \frac{15}{7} $.
---
💡 Tip: If you're unsure, count the ticks:
- From 2 → 1st tick: $ 2 \frac{1}{7} $ → This is $ \frac{15}{7} $
- So yes, it's the
first tick after 2.
✔ That’s your answer!
