Answer:
x = 10
Step-by-step explanation:
Let the missing value be x.
Therefore,
[tex]6 \frac{1}{2} - 1 \frac{x}{16} = 4 \frac{7}{8} \\ \\ \frac{6 \times 2 + 1}{2} - \frac{16 \times 1 + x}{16} = \frac{4 \times 8 + 7}{8} \\ \\ \frac{13}{2} - \frac{16 + x}{16} = \frac{39}{8} \\ \\ \frac{13 \times 8}{2 \times 8} - \frac{16 + x}{16} = \frac{39 \times 2}{8 \times 2} \\ \\ \frac{104}{16} - \frac{16 + x}{16} = \frac{78}{16} \\ \\ \frac{104 - 16 - x}{16} = \frac{78}{16} \\ \\ 88 - x = 78 \\ \\ 88 - 78 = x \\ \\ x = 10[/tex]
