Let the length of one of the shorter pieces be

. Then, we know that two of the pieces are that length, and the third piece is

. Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for

, and then plug that back in to the desired lengths:



Shorter pieces:

Longer piece:
170? I think. I don't really understand your question
Answer is A. 3 1/4 is to the left of 7/2 and 7/2 is to the left of 3.75.
With a horizontal line, they are talking about the integers from positive to negative. as you go left the numbers decrease and as you go right the numbers increase
First change 3 1/4 and 7/2 into decimals
3 1/4= 3.25
7/2= 3 1/2= 3.5
Here are your decimals from least to greatest.
3.25, 3.5, 3.75
So 3.25 (3 1/4) is to the left of 3.5 (7/2) and it is to the left of 3.75
