Answer:
40 times
Step-by-step explanation:
Number of known species of beetles: 4 × [tex]10^{5}[/tex] = 400,000
Number of known species of caddis flies: about [tex]10^{4}[/tex] = 10,000
To compare how many times more species of beetles there are than caddies flies, you could divide 400,000 by 10,000, which gives you 40.
Therefore, there are 40 times more of beetle species than caddies flies.
