Neil and Jerome were compating their heights. 

Neil measured his height and said, "I am 59 inches. 59 rounds to 100, so I am about 100 inches tall".

Jerome measured his height and said, "I am 65 inches. 65 rounds to 70, so I am about 70 inches tall. You are taller, Neil". 

Solve the problems using words and numbers.
