Question

drag the numbers into the boxes to write the equation shown by the number line. start number line with marks at 0, 1/10, 2/10, 3/10 (diamond, start), 4/10, 5/10, 6/10, 7/10 (diamond, end), 8/10, 9/10; blue arc from 3/10 to 7/10 fraction boxes: (\frac{square}{square} + \frac{square}{square} = \frac{square}{square}) number tiles: 3,4,7,10,1; 5,6,8,9,2 (arranged in two columns)

Explanation:

Step1: Identify the start and end points

The start point on the number line is $\frac{3}{10}$, and the end point is $\frac{7}{10}$.

Step2: Calculate the difference

To find the number added, we subtract the start from the end: $\frac{7}{10}-\frac{3}{10}=\frac{4}{10}$.

Step3: Form the equation

So the addition equation is $\frac{3}{10}+\frac{4}{10}=\frac{7}{10}$.

Answer:

$\frac{3}{10}+\frac{4}{10}=\frac{7}{10}$ (So the boxes should be filled with 3, 10, 4, 10, 7, 10 respectively)
