There are about 3400 species that represent 90 percent in the world what is the total number.
what is 3400/.90 ?
90%=90/100=0.9
3400/0.9=3777.777
To determine the total number of species that represent 90 percent of the world, we can use a simple proportion.
Let's assume "x" represents the total number of species in the world.
According to the information given, there are about 3400 species that represent 90 percent of the world.
This can be expressed as:
3400 is to x as 90 percent is to 100 percent.
Mathematically:
3400/x = 90/100
To solve this proportion and find the value of "x," we can cross-multiply:
(3400 * 100) = (90 * x)
340,000 = 90x
Now, we can solve for "x" by dividing both sides of the equation by 90:
x = 340,000 / 90
x ≈ 3777.78
Therefore, the estimated total number of species in the world is approximately 3778 (rounded to the nearest whole number).
