Solve Voltage Question: 3.3k & 4.7k Resistors

[Agent]

Hey, I'm stuck in one of the problems I was given. We just started it, so I'm a bit confused. It says: 3.3k resistor is in series with 4.7k resistor. Calculate the percent of the total applied voltage that would appear across the 4.7k resistor. I got this answer but I'm not sure if it is right. Thank you.

The 3.3k resistor gets this fraction of the total voltage drop:

<br /> \frac{{3.3k}}<br /> {{3.3k + 4.7k}}<br />

while the 4.7k gets this fraction:

<br /> \frac{{4.7k}}<br /> {{3.3k + 4.7k}}<br />

Don't forget to multiply by 100 to get percent.

I know where I made the mistake. I'd multiplied instead of adding. I don't know why. Thank You.
