If the original quantity is 20 and the new quantity is 16, what is the percent decrease?

2 answers:

6 0

20% Subtract starting value minus final value.
Divide that amount by the absolute value of the starting value.
Multiply by 100 to get percent decrease.
If the percentage is negative, it means there was an increase and not an decrease.

The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Given,

Number of protozoa = $5*10^5$

Number of viruses = $2*10^9$

Let,

x be the number of times number of viruses is greater than number of protozoa.

Number of viruses = Number of time * Number of protozoa

$2*10^9=(5*10^5)x$

Dividing both sides by $5*10^5$

$\frac{2*10^9}{5*10^5}=\frac{(5*10^5)x}{5*10^5}\\\\4*10^3= x\\x=4*10^3 \\x=4000$

The number of viruses was 4000 times greater than number of protozoa.
