4 (4*3=12, 4*5=20)
3/5 - 3/4 = 12/20 - 15/20 = (12 - 15)/20 = -3/20
3, -6, 12, 4, 20, ?
4 3*4 = 12 5*4 = 20 6*4 = 24
If you mean multiply then yes! Its simple actually...here's a problem: 3/4 x 4/5. All you do from there is multiply straight across:3 x 4=12 and 4 x 5=20. Put that in a fraction and your answer is 12/20...simplified: 3/5.

No, the GCF of 20 and 12 is 4. 20/12 = 5/3
The GCF is 4.
8 and 12
11/12 + 3/4 = 11/12 + 9/12 = 20/12 = 5/3 = 1 2/3
Factors of 12: 1, 2, 3, 4, 6, 12 Factors of 20: 1, 2, 4, 5, 10, 20 Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24 GCF (12, 20, 24) = 4
