The 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.
<h3>What is the percentage?</h3>
It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We are assuming:
Total number of residence in the country = 144,000
In which 900,00 residences are rentals.
Percentage of residences in the country that are rentals:
= (90000/144000)×100
= 0.625×100
= 62.5%
Thus, the 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.

1 ft= 12 in
(34*12)= 408 in
so 34 ft= 408 in
Two positive integers have gcd (a, b) = 15 and lcm (a, b) = 90. Those two numbers are 15 and 90 or 30 and 45.
Suppose we have 2 positive integers, a and b, then:
gcd (a, b) = the greatest common divisor = common prime factors of a and b
lcm (a, b) = the least common multiple = multiplication of the greatest common prime factors of a and b
In the given problem:
gcd (a, b) = 15
prime factorization of 15:
15 = 3 x 5
Hence,
a = 3 x 5 x ....
b = 3 x 5 x ....
lcm (a, b) = 90
prime factorization of 90:
90 = 3 x 5 x 2 x 3
Therefore the possible pairs of a and b are:
Combination 1:
a = 3 x 5 = 15
b = 3 x 5 x 2 x 3 = 90
Combination 2:
a = 3 x 5 x 2 = 30
b = 3 x 5 x 3 = 35
We can conclude the two integers are 15 and 90 or 30 and 45.
