Answer: 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.
