yes
divide both by 11
22/11 = 2
99/11 = 9
22/99 = 2/9
Yes.
1/3
6 5/14
11/99 divided by 11/11= 1/9
2x over 11
22/8 =11/4
22/4 = 11/2
22/32 = 11/16
You divide them by two so 22/32 becomes 11/16 and then you cannot simplify them anymore.
Yes, to 11/50
no 13 is a prime number
136 and 99 are relatively prime (they have no common divisors) so the fraction 136/99 cannot be simplified but it can be rewritten as 1.3737...
