Answer:
12
Step-by-step explanation:
We are told that the school won 75% of the games, this means that the school lost:
100% - 75% = 25%
the school lost 25% of the games that equate to 4 games:
Games Percentage
4 ⇔ 25%
I will call 'x' the number of games that they won, which is the 75%:
Games Percentage
4 ⇔ 25%
x ⇔ 75%
we can solve this problem using the rule of three: multiply the cross quantities on the table (4 by 75) and then we divide by the remaining number on the table (25), thus the number of games they won is:
x = 4*75/25
x = 300/25
x = 12
they won 12 games
Another (perhaps simpler) way to find this same result is:
we know that 25% equals 4 games,
if we want 75%, this is 3 times more than 25% (because 25% times 3 is 75%) thus, the result (number of games they won) is 3 times more than 4:
4 * 3 = 12
