I just need the answer. ( look at the picture )

Answer 1

Answer:

P * 300000 = 30

.01%

Step-by-step explanation:

Let P equal the percent.  Of means multiply and is means equals

We need to make sure the units are the same.  I will convert km to cm

3 km *1000m/1km  * 100cm/1m =300000 cm

Now we can write the equation

P * 300000 = 30

Divide each side by 300000

P 300000/300000 = 30/300000

P =.0001

Changing this from decimal to percent

P = .0001*100 = .01 %
