suppose you copy a figure on a copier using the given size factor. find the scale factor from the original figure to the copy in decimal form. a)200%, b)50%, c)150%, d)125%, e)75%, f)25%
For each, move the decimal point two spaces to the left (from the right end of the number) and remove the % sign.

To find the scale factor from the original figure to the copy, you need to divide the size of the copy by the size of the original figure. The size factor is given as a percentage, so we need to convert it to a decimal form before dividing.
a) 200% = 200/100 = 2
b) 50% = 50/100 = 0.5
c) 150% = 150/100 = 1.5
d) 125% = 125/100 = 1.25
e) 75% = 75/100 = 0.75
f) 25% = 25/100 = 0.25
So, the scale factors in decimal form are:
a) 2
b) 0.5
c) 1.5
d) 1.25
e) 0.75
f) 0.25
