No. 69.5 is half of 139. The square root will be between 11 and 12.
0.695 = 695/1000 which can be simplified to 139/200
695
6.95 = 695/100 = 139/20
There are long division methods, and guess and divide methods. I'll go over the guess and divide method. Let's assume X is the number we want the square root of. The guess and divide consists of: 1. Guessing the square root of X (the guess is now known as Y1). 2. Divide X by Y1, and then using the resulting number as the new Y2. 3. Average Y1 and Y2, giving you the new number Y1. 4. Repeat steps 2-3 until your guess Y1 is roughly equal to the average of Y1 and Y2 Here's an example sqrt 695; my first guess for the root is 25. 1. 695 / 25 = 27.8 2. 25 + 27.8 / 2 = 26.4 3. 695 / 26.4 = 26.3257 4. 26.4 + 26.3257 / 2 = 26.36285 5. 695 / 26.36285 = 26.3628553 These two numbers are about equal, so you now have a good estimate of the root of 695. 26.3628553 *26.3628553 = 695.0001 You can keep going through the process until you are satisfied with the accuracy.

1, 5, 139, 695 5 and 139 are prime.
1, 5, 139, 695
695 = 5 * 139
1, 5, 139, 695
695%% rate:= 139/20 * 100%= 6.95* 100%= 695%
0.695 = 695/1000 which can be simplified to 139/200
