1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.
1, 2, 7 and 14 all divide into both 14 and 84, without leaving a remainder.
The common factors are: 1, 2, 3, 4, 6, 12. 12 is the greatest common factor of 72 and 84. All the factors of 12 will therefore divide by both 72 and 84.
The GCF of 84, 168 and 182 is 14. You are left with 6, 12 and 13 respectively. You cannot further divide these by any common factor aside from 1
You divide both parts by their highest common factor, which is 28. That gives you 2 over 3.
call 36% one third divide 84 by 3 say 28 approx plus 10% (for 33% to 36%) =30.8 say 30 (actual value is 30)
84 divide by 112 = 0.75

Both 84 and 120 are products of 12. If you divide 84 by 12, you get 7 and if you divide 120 by 12 you get 10. Therefore 84/120 = 7/10.
