Answer:
<h2><em><u>
2/9 is the answer.</u></em></h2>
Step-by-step explanation:
<em><u>1. First, make an equation.</u></em>
<em><u>Given:</u></em>
8/9 = length of wire
2/3 = length of a part of the wire
E = 8/9-2/3
<em><u>Unknown:</u></em>
Second part of wire
<em><u>2. Make the numbers have equal denominators</u></em>
2/3 * 3/3
= 6/9
<em><u>3. Solve</u></em>
8/9 - 6/9
= 2/9

Pounds: 10  20  30
Kilos:      4.5   9  13.5
half of 20 is 10, and half of 9 is 4.5.  So every 10 pounds is 4.5 kilos.  Add 10 to 20 to get 30, and add 4.5 to 9 to get 13.5.  Both parts of the ratio table are increasing at the same rate (either 10 eachtime or 4.5 each time).
