Could you tell me the answer please it is not multiple-choice

a) 300000 b) 200 c) 20000

Step-by-step explanation:

Round so that there is only 1 sig. fig. in the answer

a) 300000 (rounded up to 300,000 not 280,000 as there would be 2 sig figs, 2 and 8)

b) 200 (rounded down)

c) 20000 (rounded up to 20,000 not 18,000 as there would be 2 sig figs, 1 and 8)

The trailing zeroes do not count as sig. figs. so the above answers all have only one sig. fig.
