Решите задачу:

$-1.25-(6.5-(1.5+(-2 \frac{1}{3} +3 \frac{7}{12} )))= \\ \\ =-1.25-(6.5-(1.5-2 \frac{1}{3} +3 \frac{7}{12} ))= \\ \\ =-1.25-(6.5-1.5+2 \frac{1}{3} -3 \frac{7}{12} )= \\ \\ =-1.25-6.5+1.5-2 \frac{1}{3} +3 \frac{7}{12} \\$

$-2.4-(5.6-(1.75+(-2 \frac{1}{6} +5 \frac{1}{4} )))= \\ \\ =-2.4-(5.6-(1.75-2 \frac{1}{6} +5 \frac{1}{4} ))= \\ \\= -2.4-(5.6-1.75+2 \frac{1}{6} -5 \frac{1}{4} )= \\ \\ =-2.4-5.6+1.75-2 \frac{1}{6} +5 \frac{1}{4} \\$
