Question

The Lady Eagles won 70% of their 30 basketball games this season. How many games did they lose?

Answer 1

They lost 9 games. (30/100)*(100-70)

Answer 2

30games=100% , so they won 70% that is mean :
100==>30
70  ==> x !!
so : x=(70*30)/100 = 21 , so they won in 21 games . 
and 30-21=9games , so they lose 9 games .
