Answer:
Ivan wrote the ratio incorrectly. The ratio should be written as the old length to the new length, so it should be 35
10
, which reduces to 7
2
. When going from larger to smaller dimensions, the change in the scale factor is a ratio that looks like an improper fraction, with a larger number in the numerator and a smaller number in the denominator.
Ivan wrote the ratio incorrectly and the scale factor is 7/2 or 3.5 if the Old length = 35 feet New length = 10 feet.
What is a scale factor?
The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
We have:
Ivan found the change in a scale factor.
Old length = 35 feet
New length = 10 feet
The length is reduced
So the scale factor should be less than 1
Scale factor = old length/new length
= 35/10
= 7/2
Thus, Ivan wrote the ratio incorrectly and the scale factor is 7/2.
