For part a, you would need to express 120% in terms of fraction. That would be 120/100. It can be further simplified to 6/5

For part b, the significant figure starts from the first non-zero digit. Since the number after the second -digit 8 is 6 (more than 5), it has to be rounded up. Hence you would get 0.0059 (2 s.f.)

For part c, 1 km = 1000m. Hence applying the conversion. 1.02 km would give you 1020m
