First, you will need to write the equation of proportion. Let W = waist size and H = hip size.
W+=+kH where k is the constant of proportionality. You need to find the value of k, so subtitute W = 32 and H = 40.
32+=+k%2840%29 Divide both sides by 40.
k+=+32%2F40
k+=+0.8 Now the equation of proportionality is:
W+=+0.8%2AH To find the ideal maximum waist size (W) for a woman with 35-inch hips, substitute H = 35.
W+=+0.8%2835%29
W+=+28inches.
