What is the rational number equivalent to 1 point 28 with a bar over 28? 1 and 6 over 97 1 and 28 over 99 1 and 8 over 33 1 and

katrin2010 [14]

In algebra, the conversion of a more complex number to a simpler mixed number is rather simple. For the repeated numbers, which are designated by the bar above them, we simply have to put over 9 for each number repeated and 0 for the non-repeated numbers.

In this item, we have 1.28 with bar above 28 signifying that the number can also be written as 1.28282828.... The mixed number is then equal to,
1 and 28/99 or 1 and 28 over 99

Therefore, the answer to this item is the second choice.

A school principal of 890 students needs to determine what percentage of students passed and did not pass a statewide examinatio

Greeley [361]

Answer:

Percentage = 66%

Step-by-step explanation:

Let the number of students that pass be P.

Let the number of students that fail be F.

Given the following data;

Total number of students, T = 890 students

P = 300 students

To find the percentage that failed;

First of all, we would determine the number of students that failed using the mathematical expression given below;

Total students, T = P + F

890 = 300 + F

F = 890 - 300

F = 590

$Percentage = \frac {590}{890} * 100$

$Percentage = 0.6629 * 100$

Percentage = 66.29 ≈ 66%

Therefore, the percentage of students that failed or didn't pass is 66%.
