Answer:

5/2 ≈ 2,5

Step-by-step explanation:

[tex] \sf (3 \frac{1}{2} - 9 \frac{3}{4}) \div ( - 2.5)[/tex]

[tex] \sf = ( \frac{7}{2} - \frac{39}{4} ) \div (- \frac{5}{2} )[/tex]

[tex] \sf = ( \frac{7 \times 2}{2 \times 2} - \frac{39}{4} ) \div ( - \frac{5}{2} )[/tex]

[tex] \sf = ( \frac{14}{4} - \frac{39}{4} ) \div ( - \frac{5}{2} )[/tex]

[tex] \sf = - \frac{25}{4} \div ( - \frac{5}{2} )[/tex]

[tex] \sf = \frac{25 \times 2}{4 \times 5} [/tex]

[tex] \sf = \frac{50}{20} [/tex]

= 5/2 ≈ 2,5

Conclusion:

Answer [tex] \sf (3 \frac{1}{2} - 9 \frac{3}{4}) \div ( - 2.5)[/tex] is 5/2 ≈ 2,5.
