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
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
It is: 18/9 = 2/1 = 2
1 1/2 - 2/9 = 3/2 - 2/9 = 27/18 - 4/18 = 23/18
2/9 divided by 18/5 is 0.1851851
4/9 = 8/18 1/2 = 9/18 Total: 17/18
18/2 = 9/1 = 9
18 / 9 = 2
16/18 - 9/18 = 7/18
4/9 x 2/2 = 8/18 5/18 + 8/18 = 13/18
