half of 260 equals 130 . half of 130 equals 65.
4 times 65 = 260
65
130 + 130 = 260
A quarter or 1/4 of 260 is 65
260/4 = 65 .... 4/260 = 0.0153846154 ..... 216/4 = 54 ..... 4/216 = 0.0185185185
√260 . . 260 can be factored as 4 x 65, so we can now put :- √260 = √(4 x 65) = √(2² x 65) = 2√65. Note that 65 is the product of two prime numbers (5 x 13) so the expression cannot be further simplified.
65 x 4 = 260 miles
1 x 260, 2 x 130, 4 x 65, 5 x 52, 10 x 26, 13 x 20, 20 x 13, 26 x 10, 52 x 5, 65 x 4, 130 x 2, 260 x 1
260 / 65 = 4 hours
1/4
