22/66 = 1/3
66/78 = 11/13
No.
8/13 can't be reduced.
66/78 = 11/13 = 22/26
39/66 both numerator and denominator are multiples of 3'3' So cancel down by '3' 39/66 = 13/ 22 This will not cancel down any further as '13' is a prime number, and '22' is NOT a multiple of 13.
66% of 13= 66% * 13= 0.66 * 13= 8.58
11/13
1/13
66% of 13= 66% * 13= 0.66 * 13= 8.58
it does not reduce down at all
You reduce it. To reduce it, you find the greatest factor they share, in this case 2, and divide each number by it, to get 13 over 14, or 13/14.
