There is no need to simplify this, it is only a sum. 21 + (10/2) - 18 = 8
It is: 21/18 = 7/6 by dividing the numerator and denominator by their HCF which is 3
18 + 3 = 21
can you simplify 18 over 44
First you find like terms so you subtract 12-9 Then you get 3a Your other like terms are 3+18 Then you get 21 So your answer is 3a+21
3x7
no
21:6::7:2
24
29 over 18 is simplified.
