Answer
Find out the how many total meters are not painted in the 208 meters of road .
To prove
Let us assume that the total meters are not painted in the 208 meters of road be x.
As given
A 208-long road is divided into 16 parts of equal length.
Each road length when divided into 16 equal parts = 13 meters
As given
Mr.Ward paints a 4-meter-long strip in each part.
Mr.Ward not paints in each part = 13 - 4
= 9 meters
Thus
Total meters are not painted in the 208 meters of road = 9 × 16
= 144 meters
Therefore 144 meters are not painted in the 208 meters of road .

Answer:
43 questions in total
Step-by-step explanation:
the original equation with the unknown (total number of questions on the test) will look like this
we know this because to work out a percentage in the 1st place you need the total ÷ number (in this case it's ÷ how many questions out of the total she did answer)
now you rearrange.
you need to move the 24 to get the total on it's own here's how you do it
what you do to one side of equation you have to do to the other. the 24 and 24 on the left will cancel because 24÷24=1 and we don't write
got mum of Q's x 1= 80 x 24
now you convert % to decimal
replace
now you take the original and + the 19
therefore there are a total of 43 questions on the exam
