Observe the following expressions: ① $\sqrt{1+\frac{1}{{1}^{2}}+\frac{1}{{2}^{2}}}=1+\frac{1}{1}-\frac{1}{2}=1\frac{1}{2}$; ② $\sqrt{1+\frac{1}{{2}^{2}}+\frac{1}{{3}^{2}}}=1+\frac{1}{2}-\frac{1}{3}=1\frac{1}{6}$; ③ $\sqrt{1+\frac{1}{{3}^{2}}+\frac{1}{{4}^{2}}}=1+\frac{1}{3}-\frac{1}{4}=1\frac{1}{12}$. According to the above three equations, the result of $\sqrt{\frac{50}{49}+\frac{1}{64}}$ is ____.
