Sarah is building a model of the school. the scale of her model to the actual school is 1 to 10. Her model is 380 in tall. How tall is the actual School?
So for this I would set up a ratio. 1/10=x/380 then you cross multiply so 1x380=10x. Then solve the equation so 380/10=x and you get 38in. Hope my explanation helped!
