<u><em>Question</em></u>
<em>If the CP of 15 articles equals to the SP of 12 articles, find the gain percent.</em>
<em></em>
Answer:
gain percent = 25%
Step-by-step explanation:
To solve the question given, we will follow the steps below:
gain% = 
× 100%
But from the question;
"CP of 15 articles equals to the SP of 12 articles", this implies that
15 c.p = 12 s.p
s.p = 15c.p / 12
s.p = 
= 
s.p =
substitute s.p = into the formula
gain% = × 100%
=
× 100%
= 
× 100%
= 
÷ c.p × 100%
= × 
× 100%
= 
× 100%
= 25 %
Answer:
C
Step-by-step explanation:
So we need to understand what is rational numbers?
Rational number which can be written under this form: 
when x any are both integers and y
The question here is : Which property would be useful in proving that the product of two rational numbers. In math, when we talk about the product of at least two number, it implies to the multiplication in the operation.
Here, only answer C: 
with the condition 
and a, b, c and d are integers. Product of two integers is always an integer..
The equivalent fraction for 0.7 is 70/100.
You know this because 0.7 is the same as 7/10.
7/10 is the same as 70/100 when we create 7 groups of 10 (numerator) and 10 groups of 10 (denominator).
Also, placing a zero to the right of any number on the right hand side of the decimal point will not change the value.
0.70 is 70/100
