5/6, 1/4, and 2/3 yard. Needs 1 yd of cable
mixer [17]
1. So first of all we have to divide the 3 fractions into decimals to get a decimal to compare. So 5/6 is the same as 5 divided by 6 which is .83 bar and so on...

5/6= .83 bar
1/4= .25
2/3= .66 bar

So 5/6 and 2/3 are closer to one.




2. The two shortest pieces are 2/3 and 1/4 so you se 1/4 + 2/3. Let’s get a common denominator for these fractions. The common denominator is 12. So multiply 1/4 • 3 to get 3/12 and multiply 2/3 by • 4 to get 8/12. Add them together and you get 11/12. So he would need 1/12 more cable or 0.083 bar.


3. Now we have to find a common denominator for all of them. The common denominator is 12 again. Multiply 5/6•2 and then you get 10/12, then add 10/12 +2/12(from 1/4) and then you get leftover with 9/12 or 3/4 more wire.

 <span>The fifth power of ten would not be represented. 
Each individual digit would be shown as a power of ten. 
982 would be the sum of: 
9 times 100. (100 is 10 to the second power) 
plus 
8 times 10. (10 is 10 to the first power.) 
plus 
2 times 1. (I is 10 to the zero power.) 

The only significant digit represented by a zero is the "hundred thousands" 
(100,000 is 10 to the fifth power.)</span>
