Final answer:
To find point E on line CD with a ratio of CE to CD of 1:4, divide the length of CD by 4 to get the length of CE.
Step-by-step explanation:
To find point E on line segment CD such that the ratio of CE to CD is 1 to 4, you would first acknowledge that CE is one part of the whole segment CD, which is divided into four equal parts. Since CE is one part and CD is the whole, the length of CE is one fourth the length of CD. This means that if you know the length of CD, you simply divide it by 4 to get the length of CE. Without the specific measurement of CD, you can represent the length of CE as CD/4.
