18 months
……33inches, weight 25.5 pounds
When
he was born = 9 months…20 inches, weight 8, 4 pounds
Every
9 months his height growth is 33-20 = 13 inches, his weight is 25.5-8.4=17.1 pounds
<span>Pounds. This means, for every 9 months, his growth is
13 inches and his weight is 17.1 pounds. For example we can determine his
growth in 3 years.</span>
<span>3
years = 36 months, 36= 9*4, his height will be 4*13 inches= 52 inches, his
weight will be 4*17.1 = 68.4 pounds </span>
<span>If you are reading a story problem that says one and a half this would indicate the mixed number 11/2 or the decimal 1.5, which are all equivalent.</span>
