First, you do a proportion. X/48=25/100. 25 times 48 equals 1,200. Now divide 1,200 by 100 which equals 12. This means 12 cookies is 25% of 48 cookies. Now do 48-12 which is 36. YOUR ANSWER IS 36

Dmitry_Shevchenko [17]

Given value:

\ Set\ X  = \{9, 25\} \\\\\ Set \ Y = \{ 1,4,9,16,25 \}\\\\Find: \\\\Set (X- Y) \\\\
