Answer:
Jose and George are correct
Baulus is incorrect
Step-by-step explanation:
Given
%
Required
Compare the above expression with
Jose: 6.75%.
George: 0.0675
Baulus: 0.0675%
<em>The expression </em><em>% is given as a mixed fraction;</em>
In Jose's case, he simply converted it to decimal
Converting % to decimal;
First, we need to convert to improper fraction
% in improper fraction is
%
Then, we divide the numerator by the denominator
% = 6.75%.
Hence, Jose is correct
In George's case, he solved further by removing the % from Jose's answer.
% means divided by 100; In other words, x% means that we divide x by 100
So, 6.75% means we divide 6.75 by 100
= 0.0675
Hence, George is also correct
But same can't be said of Baulus;
Baulus converted % as 0.0675%
This means that he converted as 0.0675 then he appended it with the percentage sign (%)
Since is not equal to 0.0675, then we can conclude that Baulus is incorrect
