Definition of a rational number:
A rational number is a number that can be written as fraction of integers.
19/10 is a fraction.
19 and 10 are integers.
19/10 follows exactly the definition of a rational number, so it is rational.
All you have to do is make and simplify a fraction. In this case, there are 6 friends going into 4 pears, so the fraction is 6/4. Then we can simplify that because they are both divisible by 2. So if we divide both by 2, our fraction becomes 3/2. Then we make that into a mixed number, with 3 going into 2 once with 1 left over. That means the answer is 1 1/2.

<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
x is the number of minutes that will be used during a month:
C₁ = 0.24x
C₂ = 49.95 + 0.11x
So, when 1st = 2nd
0.24x = 49.95 + 0.11x
0.24x - 0.11x = 49.95
0.13x = 49.95
x = 49.95/0.13
x = 384.23 minutes
Hence, If you talk for 384.23 minutes the two plans will have the same cost.
