A college basketball team won 72.5% of the games they played. If they played 80 games, how many did they win?

10% is 8, so multiply this by 7 to get 70%.

That would 56.

To get the 2% think of what 1% is then double it.

1% would be 0.8, so 2% would be 1.6

Then, to get the 0.5% just cut what 1% of it is.

Since 1% would be 0.8, you cut it in half to get 0.4.

Combine the 56, 1.6, and 0.4.

1.6+0.4=2.

So the problem would read 56+2=58.

58 is 72.5% of 80 games.
