To simplify the fraction 20 over 72, you can divide both the numerator (20) and the denominator (72) by their greatest common divisor, which is 4. This results in the fraction 5 over 18. Therefore, 20 over 72 simplified is 5/18.
eighteen 20 x 4 = 80 19 x 4 = 76 18 x 4 = 72
4 x 36 = 72 + 72 = 144 so 4 yards is 20 inches bigger
