If line segment AB is 400%, what is the length of a line segment that is 100%? inch(es) (Type a whole number or a decimal.)

Answer 1

EXPLANATION

If we have a segment AB that represents 50% we need to consider that a hundred percent is obtained by the following relationship:

50% ---------------------> 4 inches

100% ----------------------. x? inches

Applying the proportionality:

$x?inches=100\cdot\frac{4}{50}=100\cdot\frac{2}{25}=100\cdot0.08=8\text{ inches}$

The answer is 8 inches.
