The solution is k = 9.
21-4x3 is equal to 9.

no 9 + 10 = 19 11 + 10 = 21 9 + 12 = 21
assuming question is 21/27 then 21/7 = 3 = 27/9 Answer: 7/9

assuming question is 21/27 then 21/7 = 3 = 27/9 Answer: 7/9
3/7+ 9/21 is equal to (3x3)/(7x3) + 9/21 which is equal to 9/21 + 9/21 , because both denominators are the same you can simply add the two numerators which then becomes 18/21 , then yo can cancel it down to 6/7
9-6 = 3 21-13= 8 8x3 = 24
