Answer:
decrease by 35%
Step-by-step explanation:
0.65 is only 65% of a whole number, so it decreases the original number by 35%
The long piece is 4 times the length of the short piece.
Short piece = 1 time
Long piece = 4 times
--------------------------------
Full rope = 5 times
5 times = 70 inches
Divide each side by 5 : 1 time = 14 inches
<em>Short piece</em> = 1 time = <em>14 inches</em>
<em>Long piece</em> = 4 times = 4 x 14inches = <em>56 inches</em>
<u>Check:</u>
Ratio of long to short = 56inches / 14inches = <u>4</u>
Sum of both pieces = (56 + 14) = <u>70 inches</u>
