Without evaluating each expression, determine which value is the greatest. explain how you know.

latex: 7\frac{5}{6}-9\frac{3}{4}7 5 6 − 9 3 4
latex: -7\frac{5}{6}+\left(-9\frac{3}{4}\r ight)− 7 5 6 + ( − 9 3 4 )
latex: -7\frac{5}{6}\cdot9\frac{3}{4}− 7 5 6 ⋅ 9 3 4
latex: -7\frac{5}{6}\div\left(-9\frac{3}{4 }\right)− 7 5 6 ÷ ( − 9 3 4 )

the solution to example is the greatest because
