Answer:

40 times

Step-by-step explanation:

Number of known species of beetles: 4 × 10^{5} = 400,000

Number of known species of caddis flies: about  10^{4} =  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.

In a class room 3/10 of the students are wearing blue shirts and 3/5 are wearing white shirts there are 20 students In The class
shtirl [24]

Total number of students in the class = 36

Number of students wearing blue shirts = (1/6) * 36

                                                                = 36/6

                                                                = 6

Number of students wearing white shirts = (2/3) * 36

                                                                 = 2 * 12

                                                                 = 24

Then

Number of students not wearing blue or white shirts in the class = 36 - (6 + 24)

                                                                                                       = 36 - 30

                                                                                                       = 6

So 6 students in the class are wearing a shirt other than a blue or a white shirt. I hope the procedure is clear enough for you to understand.
