why you multiply by 3?
dont kno help me
what do ut hink
5 cm is 4 ft how many ft is 1 cm?
You don't need to know that.
yes you need to know you always get answer by performing this step but you may ignore it if you are good
You take the ratio of the sail height on the model to the scale of 5 cm. Then you multiply this value times the scale value of 4ft
which gives you 88 right ?
rickjbr that's what i asked for at the beginning, it's called ratio
Ah I see what you were talking about. I thought you were asking to do a metric conversion.
Sorry about that
which one is my answer
solve for x
every 5centimeter of his model stands for 4 feet so write a proportion 5cm/4 ft = 22cm/x ft
