WebA scale factor can be used to enlarge or reduce a shape. A missing length on a reduction/enlargement figure can be calculated by finding its linear scale factor. Part of … WebSince the drawing is scaled down, then the scale factor should be reduced to a fraction with a numerator of 1. Multiply both the numerator and denominator by 2 to simplify. scale factor = ½” × 2 12″ × 2 = 1 24. And finally, rewrite the fraction as a ratio. scale factor = 1 24 = 1:24. Thus the scale factor for this drawing is 1:24 .
