Ok I think you mean what is 6.4 divided by 0.8.
You can either use long division or a calculator. However since 6.4 divided by 0.8 is really the fraction 6.4/0.8 you can turn this into a much more simple problem.

Answer:
Use Pythagorean theorm.
a^2 + b^2 = c^2 (c is hypotenuse).
Let c = 5+b (because in the question it says the hypotenuse is one leg plus 5 more meters) ; we will solve for b and say it's the leg we don't know.
We will say A is the "other leg" we know, which is 6.
6^2 + b^2 = (5+b)^2
We get b = 1.1
Answer:
Two integers are relatively <u><em>primes</em></u> if and only if their only common positive integer factor is 1.
Step-by-step explanation:
The prime number is one whose only divisor is 1 and itself.
The prime factors of a whole number are the exact prime divisors of that whole number. In other words, every composite number can be written as a multiplication of two or more prime factors.
So, two integers are relative primes if they have no prime factor in common, or, put another way, if they have no common divisor other than 1.
So, <u><em>two integers are relatively primes if and only if their only common positive integer factor is 1.</em></u>
