Answer:
126=01111110
Explanation:
To solve this you simply have to get the sum of all your numbers to be equal to the number on the left using the biggest numbers possible
For 126,
First you look at 128, since 128>126 we can't use this and leave it as 0
126>64 so we put that as 1
We then subtract this 64 from 126 and get 62
Since 62>32 we put 32 as 1 and subtract 32 from 62
Then we see that 30>16 and put 16 as 1 and subtract 16 from 30
Now we have 14, since 14>8 we put 8 as 1 and subtract 8 from 14
Now we have 6, since 6>4 we put 4 as 1 and subtract 4 from 6
Lastly we have 2==2, since 2 can go into 2 we would put 2 as 1 and then subtract 2 from 2
Now we have 0 left and don't have to do anything with 1, so we leave it as 0
When you put it all together, you get 01111110
