Well, we first know that Dominic uses 1/2 tablespoon. So if we use that 1/2 tablespoon on two sandwiches how many tablespoons does Dominic use? A whole! If you make another two sandwiches, then it will make another whole, and I whole plus one whole equals two wholes. Then, you make another one which uses another 1/2. And 1 whole plus one whole plus 1/2 a tablespoon equals 2 1/2!
Find the length of MN by setting up a ratio:
Let MN = X
X/18 = 5/6
Cross Multiply:
6x = 90
Divide both sides by 6:
x = 15
Now you know MN add it to LM for the total length of LN:
15 + 5 = 20
The fact for Dons second array is that all he did was divide the second array in half.(4×7=28). (2×7=14). ( 28÷2=14). Hopefully that made sense!!!!!
4 I think i'm sorry if I get it wrong. Hope I helped ≥ω≤

16-4=12
12/2=6
It's not that hard of a problem you just have to read in-between the lines
