Can someone help me with proportions?

@madibear12 What do you want to know? :)

OpenStudy (anonymous):

A scale 15:1 cm. If the actual is 8cm how long it is?

OpenStudy (anonymous):

Would it would 15*8?

OpenStudy (anonymous):

\[\frac{ 15 }{ 1cm } = \frac{ x }{ 8cm }\] By cross multiplying, you will get, x=120. And yes, it is 15x8. Great job! :)
