2 x 2 x 13 x 13
Prime factors: 2, 2, 2, 3, 5, 13 Other factors are combinations of the primes, i.e. 2 x 2 = 4 2 x 3 = 6 2 x 2 x 2 = 8 2 x 5 = 10 2 x 2 x 3 = 12 3 x 5 = 15 2 x 2x 5 = 20 2 x 2 x 2 x 3 = 24 2 x 13 = 26 2 x 3 x 5 = 30 3 x 13 = 39 2 x 2 x 2 x 5 = 40 2 x 2 x 13 = 52 2 x 2 x 3 x 5 = 60 5 x 13 = 65 2 x 3 x 13 = 78 2 x 2 x 2 x 13 = 104 2 x 2 x 2 x 3 x 5 = 120 2 x 5 x 13 = 130 2 x 2 x 3 x 13 = 156 3 x 5 x 13 = 195 2 x 2 x 5 x 13 = 260 2 x 2 x 2 x 3 x 13 = 312 2 x 3 x 5 x 13 = 390 2 x 2 x 2 x 5 x 13 = 520 2 x 2 x 3 x 5 x 13 = 780
13 *2 to the second power
13 x 1/2= 13/1 x 1/2= 13/2= 6.5
9 x 3/2 = 27/2 = 13 and a half
13/15 x 1/2 = 13/30
(1/2) x (3-1/4) = (1/2) x (13/4) = 13/8
1 x 52, 2 x 26, 4 x 13, 13 x 4, 26 x 2, 52 x 1
13
13 = 13 is a prime number 52 = 2 x 2 x 13
9/2 x 7/13 = 63/26 or 2 and 11/26
One half X = 13 Double both sides: A whole X = 26 So, answer: X = 26
Prime factors are: 2, 2, 13, 13 Others can be any combination of the primes, i.e. 2 x 2 = 4 2 x 13 = 26 2 x 2 x 13 = 52 13 x 13 = 169 2 x 13 x 13 = 338
2 x 2 x 13 x 13
six and one half = 13/2 dividing by a fraction is same as multiplying by fraction turned upside down so 13/2 divided by 1/3 = 13/2 x 3/1 = 39/2 = nineteen and one half
