1.Simplified each one
2/5 (both divided by 7) , 1/2 (divided by 21)
2.Make them into integer
(2/5 )*(2/2)=4/10 , (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5
25/5 as a mixed number would be 5.
It’s will be (-3x+5)
Because u have to divide bc it’s half
This would be all the factor pairs of 18:
1 by 18
2 by 9
3 by 6
6 by 3
9 by 2
18 by 1
