1*2*2.5 =2*2.5
=5
5 is your answer
2/25
(1/2) / (2/25) = (1/2) * (25/2) = 25(1/2) / (2/25) = (1/2) * (25/2) = 25(1/2) / (2/25) = (1/2) * (25/2) = 25(1/2) / (2/25) = (1/2) * (25/2) = 25
15 goes into 25 1.66... (recurring) times.
10
12 with remainder 1 or 12.5 times.
25 x 1 = 25
25 and 1/3 x 6 = 76 x 2
5/2 x 5/4 = 25/8 = 3 and 1/8
1 is smaller than 2, so yes.
As a mathematical problem, 25, because 50/2 = 25. As a puzzle, the answer is 1, because after you have subtracted 2 once, the number you are subtracting from is no longer 50.
Let the unknown number be x: 8x+1 = 2x+25 8x-2x = 25-1 6x = 24 x = 4
1 x 50, 2 x 25, 5 x 10, 10 x 5, 25 x 2, 50 x 1
