In the 1st pair of fours the 4 on the left side is 10 times greater than the 4 on the right. The same thing with the 2nd pair of fours. The 4 on the left side is 10 greater than the 4 on the right. Hope this helps!
2n+8 maybe try that i dont get the question..kinda confusing
15-4 = 11
11 x 2 = 22
22 + 2/3 = 68/3
In order to answer this, we need an image to be able to see what they look like.
