alguien me ayuda porfavor​

Answer 1

Respuesta:

Explicación paso a paso:

-3/5+2/3=-9+10/15=1/15

-10/7x-14/2=10/7x14/2=10/7x2=10

-2/9-3/4=-8-27/36=-35/36

-3/5:2/3=-9/10

(-2/3+1/5)x-4/7=-7/15x-4/7=1/15x4=4/15

3/4-(5/3:3/4)=3/4-20/9=27-80/36=-53/36

(-3/4:-1/3)+(-4/5;2/3)=(3/4x3)+(-4/5x3/2)=9/4+(-2/5x3)=9/4+(-6/5)=9/4-6/5=45-24/20=21/20
