9 over 11.
66/78 = 11/13 = 22/26
4/11
"Percent" means "out of" or "over" 100, so put it over "100" and simplify: 78% = 78/100 = 39/50
66% percent really means 66 over 100. Then, you just have to simplify the fraction 66/100 to get 33/50
66/78 = 11/13

66/12 in its simplest form is 11/2
"Percent" means "out of" or "over" 100, so put it over "100" and simplify: 78% = 78/100 = 39/50
78/5. divide both by 7
66% percent really means 66 over 100. Then, you just have to simplify the fraction 66/100 to get 33/50
11/13
78/91 u cannot simplify it
21 over 66 is 21/66, and to simplify you must find to common factors of the two numbers ( the denominator and the numerator). a common one in this case is 3. 66 divided by 3= 22 and 21 divided by 3=7So the answer is 7/22 (7 over 22)
The LCM is: 12,870
