there are 300,000 species of angiosperms on earth and 840 species of gymnosperms. what percentage of seed plants are angiosperms
?
1 answer:
First, we're going to add the species of angiosperms and gymnosperms together.
300,000 + 840 = 300,840
Then we're going to multiply 300,840 by 300,000.
300,840 x 300,000 = 9.0252E10
We're going to round the hundredth to the tenth now.
9.0252E10 = 9.0
This is how we know 9% is angiosperms and 91% is gymnosperms.
Your answer to this question is 91%.
Hope this helps!~
