4(-5)(-2)(-9)=

6/6÷9=

1-3-5-7+5+8+2+4=

-6÷5÷7÷-2=

(4/7)(-3/5)(-7/2)=​

Answer 1

Respuesta:

1. 6/5+5/7-1 = 42/35+25/35-

35/35=67/35-35/35=32/35

2. 3÷2÷2÷−7=−0.1071429

3. 4(−5)(−2)(−9)=−360

4. 6/6:9=6/54 simplificación

:6/64=3/32=1/32

5. 1−3−5−7+5+8+2+9=10

6. −6÷5÷7÷−2=0.08571429

7. (4/7) (-3/5) (-7/2) = (40/70) (-42/70)

(-245/70) = - 247/70
