What is 34% of 20?

To calculate 34% of 20, you can use the formula for finding a percentage of a number, which is to multiply the number by the percentage expressed as a decimal.

First, convert the percentage into a decimal. Since 34% is the same as 34 divided by 100, it becomes 0.34.

Next, multiply this decimal by 20:

0.34 × 20 = 6.8.

This calculation confirms that the correct result is 6.8. Thus, the answer aligns perfectly with the method used to determine the percentage of a number, making it the right choice.

The other options do not reflect this calculation. For instance, 16.6 and 68.0 are incorrect because they represent other calculations or proportions altogether. Likewise, .680 seems like it could represent a value but is not the correct context for this percentage question.
