When you multiple a whole you just multiple straight across when you multiple a decimal you you go from right to left starting with the first number on the right then go to the top next then the next then take the next number on the bottom and do the same thing
Hope this helps you

The total area of Ohio is 4.5 * 10^4 square miles.The total area of Ohio is about how many times the total area of Rhode Island?

Answer:

The total area of Ohio is about 30 times the total area of Rhode Island

Step-by-step explanation:

Let

x -----> the total area of Ohio in square miles

y -----> the total area of Rhode Island in square miles

we know that

$x=4.5*10^{4}\ mi^{2}$

$y=1.5*10^{3}\ mi^{2}$ (searched in Google)

To find out approximately how many times the total area of Ohio is compared to the area of Rhode Island, divide the area of Ohio by the area of Rhode Island

$\frac{x}{y}$

substitute the values

$\frac{4.5*10^{4}}{1.5*10^{3}}=(\frac{4.5}{1.5})( 10^{4-3}) =3*10^{1}=30$

therefore

The total area of Ohio is about 30 times the total area of Rhode Island
