To find 198.8% of 374, you can use the formula:
\[ \text{Percentage} = \left(\frac{\text{percentage value}}{100}\right) \times \text{whole number} \]
In this case, you have:
\[ \text{Percentage} = \left(\frac{198.8}{100}\right) \times 374 \]
Calculating that gives:
\[ = 1.988 \times 374 \] \[ = 743.512 \]
Now, rounding to the nearest hundredth, you will get:
\[ 743.51 \]
Thus, 198.8% of 374, rounded to the nearest hundredth, is 743.51.
