Question

If your machine takes up 350sq. ft. and you are asked to scale down a drawing onto a 8" x 10" piece of paper what is your percent of change?

Answer 1

the scale is 630:1 = 0.16%

80inch^2 of 50400inch^2 however = 0.16%

Explanation:

350ft^2 = 50400inches 8 x 10 = 80inches = 50400/80 = 630

50400/9 =5600 we distribute

5600/80 = 7

showing us that 7 x 9 = 63 where 63 x 80 = 5040 1/100th

1 = 630

7x9x 80 = 1/100 of 50400

0.01589 x 7x9x80x 7x9x80 = 80

Proves that every every 10000 the percentage goes down 0.00011%
