3 is what i think
well the answer isn't exactly 3 feet, but it's very close at 2.91
first we convert all values to decimals to save time.
to convert a mixed number to a decimal you divide the numerator by the denominator and put the whole number in front of it
now we subtract the original value (7 7/8 or 7.875) from all the cut pieces to find out how much is left.
and there you go.
if on increasing ( decreasing ) x there is increase ( decrease) in y
that is if there is same change in one variable on changing another in same proportion . then x and y are said to be in direct proportional.
on the contrary
if on increasing ( decreasing ) x there is decrease(increase) in y
that is if there is same change in one variable on changing another in same proportion . then x and y are said to be inversely proportional.
