<span>miles per gallon uses ratios. Say your car was doing 80 miles for 4 hours. You would have the ratio 80;4 and you need to find the miles per 1 hour</span>
Area is base x height over 2
64 x 7.3 = 467.2
467.2/2 = 233.6
the area is 233.6m^2
The number is -30
Exp
2/3=-20
1/3=-10
3/3=-30
Know that dividing by 3 is the same as multiplying by 1/3.
Thus, 8/5 * 1/3 = 8/15
