Answer 1

OI.

(+4/5)÷(+4/15) = + 4/5 x 15/4 = 60/20 : 20 = 3
(+2)÷(-10/3) = + 2 x – 3/10 = - 6/10:2 = -3/5
(-5/8)÷(-10) = - 5/8 x -1/10 = 5/80:5 = 1/16
(-3/4)÷(-9) = -3/4x-1/9 = 3/36:3 = 1/12
(-3/8)÷(+3/16) = -3/8 x + 16/3 = -48/24:24 = - 2
(-2/5)÷(+0,1) = -2/5x +10/1 = - 20/5:5 = - 4
(+4/3)÷(-4) = + 4/3 x -1/4 = - 4/12:4= - 1/3
(+0,5)÷(-5/6) = + 5/10 x – 6/5 = - 30/50:10 = - 3/5
(+10)÷(+12) = + 10/12:2 = +5/6
(-2/9)÷(+4/9) = -2/9 x +9/4 = -18/36:18 = - 1/2
(-2/5)÷(-3) = -2/5x-1/3= + 2/9
(+8)÷(+1/6)= +8/1x +6/1 = + 48:1= + 48
(+15)÷(+6) = + 15/6
(-0,9)÷(+1,2) = -9/10x+10/12=-90/120:30=-3/4

Espero ter ajudado.
