A blueprint for a picnic table has a scale of 1:20. The table in the blueprint is 3 in. long. What is the length of the actual picnic table?

Respuesta :

If we examine the ratio given we can start to find the answer, 

1:20, 3:? Multiply 3 by 20, 

If 1 inch is 20 then if we have 3 inches then we will have 60
