An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.
We have the following number:
23.5
This number can be written as:
23 + 0.5
Or:
23 + 1/2
So, the new expression gives us two new numbers. In this way, we can say that:
23 = Twenty three
1/2 = a half
In conclusion, the number 23.5 can be written as follows:
<em>23.5 = Twenty three and a half</em>
Answer:
B
Step-by-step explanation:
The total number of marbles in the bag is 3 + 6 + 7 = 16
The number of green marbles is 7
The probability is 7/16
1425/100=(57•25)/(4•25)
=57/4
=14 1/4
The area under a graph is given by the integral of that function, evaluated in the interval of interest:
