The function is the Sine Curve
y = sine (x)
4/1 / 5/2 = 4/1 * 2/5 = 8/5
1 7/8 = 15/8
15/8 * 8/5 = 120/40 = 12/4 = 3 inches
shorter side should be 3 inches
.0075 is simplest... or .0075/1 if it needs to be a fraction i guess
40 percent 3/5 equals 60, 5/5 equals 100, 100-60 equals 40 percent
C - Parenthesis first (3-1)=2, then distribute the 4. 4x2=8, next add 5, 8+5=13.
