Explain how to draw a double number line representing a 1:4 ratio.

This question is math, but here is the answer.

To make a double number line, you start with two number lines and line them up at 0. You know that the ratio of the width of the original photograph to its length is 5:7, so you would make one tick mark on the top line at 5 and another tick mark on the second line at 7, making sure that the 5 and 7 are lined up.

well you would first start with 0 over 0 then it would be 1 over 4 then so on

Explanation:

i think so.
