Answer:

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
