Jose wants to build a model of a 180 m tall building he will be using a scale of 1.5 to 3.5meters how tall will the model be round your awnser

The answer would be 77.1428571 you did not specify what number to round to so to the nearest whole is 77. The tenths is 77.1. The hundredths is 77.14. The thousandths would be 77.143. I think that should cover it.
The steps would be as follows.
1. Put 180 over 3.5 like a fraction and set it equal to x over 1.5.
2. Cross multiply, so that would be 180 by 1.5 and 3.5 by x. The result is 3.5x=270.
3. Divide by 3.5
4. Your answer should be 77.1428571.

I’m confused as to what you are asking 66 2/3 percentage wise
