Write the ratio 20 inches to 3 feet using fractional notation. Simplify the fraction to lowest terms. Use 1 foot = 12 inches to first write feet as inches

Answer 1

20 inches : 3 feet
Since 1 foot = 12 inches, we can convert the feet to inches:

3 feet = 3 x 12 = 36 inches

So the ratio can be written as:
20 inches : 36 inches

Now, we can simplify this ratio by dividing both numbers by their greatest common factor, which is 4:

20/4 : 36/4
5 : 9

Therefore, the ratio 20 inches to 3 feet in fractional notation simplified to lowest terms is 5/9.
