there are 4 walls which means (8*12)*4-(3*7.5)-(4*5) is the total amount needed to be painted
(8*12)*4-(3*7.5)-(4*5)=341.5
341.5/125=0.276
0.276≈1 so the ans is A) 1
A percentage is a way to describe a part of a whole. The missing percent on the bar model is equal to 12.5%.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
On the percent bar model, above the missing percentage, the fraction is given as 1/8.
Now, the given fraction 1/8 in the form of percentage can be written as,
1/8

The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10
