N:7=x remainder 2
⇒ n= 7*x +2
4n= 4*(7x+2)=28x+8=28x+7+1=7*(4x+1)+1
⇒ the remainder is 1
Answer:
4.5
Step-by-step explanation:
because if you divide 54 and 36 you get 1.5 and 1.5 x 3 is 4.5
3:1

First off, you didn’t really ask a question you just told us what the thickness of the wood pieces are. But if you are trying to get a equal denominator you first write out the two fractions side by side and find a common denominator.
3/4 and 2/3
The lowest common denominator between 4 and 3 is 12 so in the first equation you multiply both the top and bottom by 3.
3/4 —> 3 times 3 is 9 and 4 times 3 is 12.
To make it 9/12
The second equation you do the same to make both the denominators equal but this time you multiply them by 4.
2/3 —> 2 times 4 is 8 and 3 times 4 is 12.
Making it 8/12
So side by side the two piece of wood started out as
3/4 and 2/3
But the first piece is bigger as it turned into
9/12 and 8/12
It's probably the first one: "People responded to Earth Day with letters..."
Since it's more of a detail that supports a fact, it's not as important as the other three.
