Solve for the missing number in the number bond diagram: 9 5/8 = 8 1/8 + X

This problem uses a number bond diagram. In this type of diagram, the larger of the two bottom numbers is typically the sum of the smaller bottom number and the top number.

Let the missing number in the red circle be $X$.
The given numbers are:

• Top number: $8\frac{1}{8}$
• Bottom left number: $9\frac{5}{8}$
• Bottom right number: $X$

Since $9\frac{5}{8}$ is greater than $8\frac{1}{8}$, we assume $9\frac{5}{8}$ is the sum of $8\frac{1}{8}$ and $X$.
