8+4 = 12. Therefore, 12 - 4 must equal 8 ,right?
And if 4+4+4 (4x3) =12, and you take away 1 group of 4, you will have
two groups of four right? and two groups of four (4x2) must equal 8 ,right?
From One Smartie to Another- BubbleSmartie11
Area= length * width
Therefore, you do 3*1/8
ie 3/8
idk if its right :/
This is what I did to get my answer
If PQ=7 and QR=10,
P=(7/Q) and R=(10/Q)
Therefore:
PR=(7/Q)(10/Q)
=(70)/Q²
