Answer:

864 squared meters

Step-by-step explanation:

Set up a proportion.  The scale between 270 and 360 should be the same as 648 to the fourth yard.

\frac{270}{360} = \frac{648}{x}\\270x = (360)(648)\\270x = 233280\\x = 864 m^2

Is 3/10 greater than or less than 1/2
V125BC [204]
To compare two fraction we have to make common denominator, then we can compare numerators.
Lets do this
\frac{1}{2}= \frac{1*5}{2*5}= \frac{5}{10}
Now we can compare numeratos.
3<5, so 1/2 is greater than 3/10.
