90/1

Step-by-step explanation:

Change the feet to inches. 150 ft is 1,800 inches.

It now looks like this:

1,800:20

Reduce it:

Try to always reduce it until it cannot be reduced anymore. The highest we can go where both are able to be reduced EQUALLY is 20.

1,800 divided by 20 equals 90.

20 divided by 20 is equals 1

Therefore the ratio is 90:1

the probability is 0
