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>
Answer: -4/15
Step-by-step explanation: To add these two fractions together,
we start by finding their <em>Least Common Denominator</em> (LCD).
Since our denominators of 5 and 3 have no factors in common,
our least common denominator is 5 · 3 or 15.
In order to get a denominator of 15 in each fraction,
we multiply top and bottom of the first fraction by 3
and top and bottom of the second fraction by 5.
That gives us -9/15 + 5/15 which simplifies to -4/15.
As your last step, make sure that the fraction
that you end up with doesn't reduce.
In this case, -4/15 does not reduce but watch out for this last step.
