Answer: 10%
Step-by-step explanation:
The difference between his estimated and actual distance is 15 - 13.5 = 1.5
The percentage of error is the difference divided by the actual value.
1.5÷15 = 0.10
Converted to a percentage, it is 10%
I'm guessing you need 43/645 simplified:
First, we need to find the greatest common factor (GCF) of the numerator (43) and the denominator (645). To do so, we list all the factors of each number and find the common ones.
Factors of 43: 1, 43
Factors of 645: 1, 3, 5, 15, 43, 129, 215, 645
Out of the listed factors for each number, which numbers are common between the two? The common factors are 1 and 43. Since we are looking for the GREATEST common factor, which number out of 1 and 43 is the greatest? The GCF is 43.
Second, we can now divide the numerator (43) and the denominator (645) by the GCF we recently found which was 43.

Third, our new simplified fraction is 1/15. We collected our new numerator and denominator.

Answer in decimal form:
There is no diagram, so you should guess C. C is the most likely to be chosen as an answer.
67:938
But when you reduce this ratio your final answer is 1:14
