C 16 is correct Bc if u solve it out it Becomes to 16 put -6 under 2 and 12 cross out 2-6 and add 12 and 6 witch gives u 16.
Whats up? What do you need help with
The 3 numbers could be 0.5, 1.1 and 4.4.
In the list above, there is only 1 number less than 1. It is 0.5.
The other 2 numbers are larger than 1.
If you add up the 3 numbers you will have exactly 6.
0.5 + 1.1 + 4.4 = 6
as you can see you have to use commutative property given !!!!!!!!!
Simplify to 2/1 x 10 = 20.
