214 is the answer...
1. 10
2. 4
3. 0.51
4. 2.67
5. 1.2
6. 0.5
1. 3/8 + 2/8 = 5/8 = 0.625
0.625 * 16 = 10
2. 7 - 1 = 6
6 * 3 = 18
72/18 = 4
3. 1/12 = 0.08
4 * 0.08 = 0.32
5/6 = 0.83
0.83 - 0.32 = 0.51
4. 2.3 + 1.7 = 4
4 * 3 = 12
32/12 = 2.67
5. 6.3 - 5.1 = 1.2
0.7 + 0.3 = 1
1.2 * 1 = 1.2
6. 0.5 * 0.5 = 0.25
0.25/0.5 = 0.5
