The evaluation of 84 2/3% to a fraction in its lowest term is 
<h3>What is a fraction?</h3>
Fractions are sections or parts of a whole. They are divided into two parts, the numerator, and the denominator.
From the given information, we are to convert a mixed fraction into its lowest terms. By doing that, we are to convert it to an improper fraction.
Divide both the numerator and denominator by (2)

Answer:
4√7
Step-by-step explanation:
5√7 + √7 - 2√7
Taking out common term, √7.
= √7 ( 5 + 1 - 2)
Simplify the terms in the bracket.
= √7 (4)
= 4 √7
Given: 48 students took the exam.
A total of 18 + 10 = 28 students scored 80% or above.
To find the percentage, take the part (28 students) divided by the whole (48 students) then multiply the quotient by 100.
(28 students / 48 students) x 100 = 58.33%
58.33% of the students who took the exam scored an 80% or higher
Answer:
b. (2, 5, 3)
Step-by-step explanation:
Trying the offered choices seems the fastest way to find the answer. The second choice works in all equations, hence is the solution.
Another strategy you can use is to see if the equations are dependent. Here, it looks like adding twice the third equation to the other two eliminates at least the x- and y-variables. If that eliminates z, then there are infinite solutions. Instead, it gives the equation ...
7z = 21
z = 3 . . . . . divide by 7
This answer is consistent with choice B, confirming that answer and eliminating the other choices.
