Step-by-step explanation:

1) - 12:2/3 = - 12 * 3/2 = - 6*3 = - 18

2) - 8/3:7/12 = - 8/3 * 12/7 = - 8*12 / 3*7 = - 96/21

3) 8.64: (-0.27) = 8.64/-0.27 = 8.64*100/-0.27*100 = 864/-27 = - 32

4) The submarine's depth relative to sea level after the first minute = - 3/4 divided by 5

= - 3/4 * 1/5 = -3/20 = - 0.15 miles
