You are given the percentage of the whole integer that is the number less then one, for example 37 * 0.15 = 5.55, because 15% of 37 is 5.55
Given:
Expression is
To prove:
If r is any rational number, then is rational.
Step-by-step explanation:
Property 1: Every integer is a rational number. It is Theorem 4.3.1.
Property 2: The sum of any two rational numbers is rational. It is Theorem 4.3.2.
Property 3: The product of any two rational numbers is rational. It is Exercise 15 in Section 4.3.
Let r be any rational number.
We have,
It can be written as
Now,
3, -2 and 4 are rational numbers by property 1.
is rational by Property 3.
are rational by Property 3.
is rational by property 2.
So, is rational.
Hence proved.
Okay ...
you do the opposite
so you do
38-15=23
that would leave you with
7x=23
you then get x on its own by dividing 7x by 7
and because you divided one side yo must divide the other ..
so
23/7 =
3.2857
x=3.3
