Santos flipped a coin 300 times. The coin landed heads up 125 times. Find the ratio of heads to total number of coin flips. Express as a simplified ratio.

Ratio is : - Heads: number of coin flips

So now we plug in the numbers.

A ratio compares two values.

Ratio: 125:300

Now we simplify by dividing both values by the same number.

125:300 =

125/5 = 25

300/5 = 60

We aren't done yet, because we can still simplify more.

25:60=

25/5 = 5

60/5 = 12

Our final ratio: 5:12

The first ratio is 125:300

Divide by 5

25:60

Divide by 5 again

5:12
