On a blueprint the Length of a wall is 5 cm is the actual length of the wall is 15 feet what is the scale of the blueprint
its three think about it if the length of the wall is 5 cm and the actual is 15 what do you multiply 5 to get that answer. 3 so each cm equals 3
:3
*this is probably the wrong way to do it but its easier

no lies these are 100% correct
good luck out there my kings and queens
To determine the scale of the blueprint, you need to find the ratio between the length on the blueprint and the actual length of the wall.
In this case, the length on the blueprint is given as 5 cm and the actual length of the wall is 15 feet.
1. Convert the actual length of the wall from feet to centimeters, as the length on the blueprint is given in centimeters. Since 1 foot is equal to 30.48 centimeters, the actual length of the wall in centimeters is:
15 feet * 30.48 cm/foot = 457.2 cm
2. Now that you have the actual length of the wall in centimeters, you can determine the scale of the blueprint by finding the ratio between the length on the blueprint and the actual length of the wall:
Scale = Length on the blueprint / Actual length of the wall = 5 cm / 457.2 cm
Simplifying this ratio gives the scale of the blueprint.
Make a ratio comparing the two values; you can use either 5:15 or 15:5
A ratio, as always can be written as a fraction, like this:
5/15 or 15/5
Simplify the fraction:
1/3 or 3
Convert back into ratio:
1:3 or 3
Depending on the type of ratio you need, you can use either one.
Hope this helps!
