1/2 + 1/9 = 9/18 + 2/18 = 11/18
1/9 = 2/18 3/6 = 9/18 2/18 + 9/18 = 11/18
2/9 × 18 = (2×18)/9 = 36/9 = 4 Alternatively, cancelling as you go: 2/9 × 18 = (2×18)/9 = 2×(18/9) = 2×2 = 4
2/9 divided by 18/5 is 0.1851851
4/9 = 8/18 1/2 = 9/18 Total: 17/18
It is: 18/9 = 2/1 = 2
1 1/2 - 2/9 = 3/2 - 2/9 = 27/18 - 4/18 = 23/18
16/18 - 9/18 = 7/18
2/3 + 1/9 + 5/6 = 12/18 + 2/18 + 15/18 = 29/18 = 111/18
-2/9 + 5/6 = -4/18 + 15/18 = 11/18
divide 2 into both 2/2 = 1 18/2 = 9 so 2/18 = 1/9
2 over 9 divided by 4 over 7 is the same as 2 over 9 times 7 over 4 which is... 7 over 18 ....so the answer is 7 over 18
4/-9 − 5/2 = -53/18 or -217/18
Half of 18 is 9
18/18 and 27/27
18/27 = (2×9)/(3×9) = 2/3
4/9 = 8/18 and 2/6 = 6/18, so 4/9 is bigger
