Answer :
first we have to find common denominators. 3x=7/8, or 3x=14/16
1/4=4/16
14-4-3=7, all over 16
7/16
1/4=4/16
14-4-3=7, all over 16
7/16
The length of the third board is [tex]\frac{7}{16}[/tex].
Given that,
- There is a total length of three boards is 7/8 off a yard.
- And, the length of two of the boards is one-fourth and third-sixteen.
Based on the above information, the calculation is as follows:
[tex]= \frac{14-4-3}{16}[/tex]
[tex]= \frac{7}{16}[/tex]
Here we have determined the common denominators.
Therefore we can conclude that the length of the third board is [tex]\frac{7}{16}[/tex].
