To find out what 90 of 20 means, we need to interpret it as calculating 90 percent of 20.
To calculate this, we can use the formula:
Percentage Value = (Percentage / 100) * Total
In this case, the percentage is 90 and the total is 20. So we can set it up like this:
90% of 20 = (90 / 100) * 20
This simplifies to:
0.9 * 20 = 18
Therefore, 90 of 20 is equal to 18.
