That probably refers to the ratio between the length of the ladder, and the distance at which you place the bottom part of the ladder from the wall. If this distance is too short, you have the risk of the ladder falling backwards.

generally a 4:1 ratio is suggested (25%)
The ratio is 1:25 4 percent as a ratio is 0.04 : 1
It is 1/4.
The ratio of their surface areas is the square of the ratio of the lengths. Since the ratio of the lengths is 4-1, then the ratio of the surface areas is 4^2-1^2 or 16-1.
The similarity ratio is 1:4.
25% = 1/4 The ratio would be 1 to 4.
A ratio of 2:4 is the same as a ratio of 1:2
Since 16/16 = 1 and 64/16 = 4, the ratio is 1/4 or 1 to 4
1 pound = 16 ounces. 1 ounce = 1/16 pounds 12 ounces = 12/16 pounds OR 12 ounces = 3/4 ounces Therefore, we will use the ratio 3:4
Use vinegar and hot water ratio 1:4.
1:4 1 to 4
