There are about 3,400 species of frogs and toads, and scientists tell us that they represent 90% of the amphibians in the world. Using this information, what is total number of amphibians scientists believe are in the world. (Round your answer to the nearest 100.)
3400/90% = 3777
round to nearest 100 so answer is:
3700
The nearest hundred would actually be 3800. But the answer is completely wrong.
3400 x .9 = 3060.
Nearest hundred is 3100.
thanks for the correction the answer is 3800 otherwise that makes no sense. the question is asking for how many amphibians there are in the world and the 3400 represents 90% of all amphibians in the world. The answer can not be less then 3400 since that's not even logical.
To find the total number of amphibians believed to be in the world, we need to use the information given. We know that there are about 3,400 species of frogs and toads, which represent 90% of all amphibians.
First, let's determine the total number of amphibian species. We can do this by dividing the number of frog and toad species by their percentage representation:
3,400 species / 90% = 3,400 species / 0.9 = 3,777.78 (rounded to the nearest whole number)
Next, let's find the total number of amphibian species in the world. Since frogs and toads represent only 90% of all amphibians, we can calculate the total using the formula:
Total Amphibian Species = Amphibian Species / 0.9
Total Amphibian Species = 3,777.78 species / 0.9 = 4,197.53 (rounded to the nearest whole number)
Therefore, scientists believe there are approximately 4,200 (rounded to the nearest 100) amphibian species in the world.
