Answer

Simplify the equation: \(\frac{10}{16} + \left(-\frac{3}{4}\right) = \frac{5}{8} - \frac{3}{4} = \boxed{-\frac{1}{8}}\)

Steps

Step 1 ：Find the LCD and GCF for 10 and 16: \(\text{LCD} = 80\), \(\text{GCF} = 2\)

Step 2 ：Simplify the equation: \(\frac{10}{16} + \left(-\frac{3}{4}\right) = \frac{5}{8} - \frac{3}{4} = \boxed{-\frac{1}{8}}\)
