[tex]\frac{19}{6}[/tex] many more miles of road are left to build .
Step-by-step explanation:
Here we have , A construction crew must build 4 miles of road in one week. On Monday, they build 1/2 mile of road. On Tuesday, they build 1/3 mile of road. We need to find that How many more miles of road are left to build . Let's find out:
Let Miles of road left to build is x So,
⇒ [tex]\frac{1}{2} +\frac{1}{3} +x = 4[/tex]
⇒ [tex]x = 4 - (\frac{1}{2} +\frac{1}{3})[/tex]
⇒ [tex]x = 4 - (\frac{1(3)+1(2)}{6} )[/tex]
⇒ [tex]x = 4 - (\frac{5}{6} )[/tex]
⇒ [tex]x = (\frac{4(6)-5}{6} )[/tex]
⇒ [tex]x = \frac{24-5}{6}[/tex]
⇒ [tex]x = \frac{19}{6}[/tex]
Therefore, [tex]\frac{19}{6}[/tex] many more miles of road are left to build .
