# In center

What number lies in the center between a quarter of a fifth and a half of a third on the number axis?

Result

x =  0.108

#### Solution:

$a = \dfrac{ 1 }{ 4 } \cdot \ \dfrac{ 1 }{ 5 } = \dfrac{ 1 }{ 20 } = 0.05 \ \\ b = \dfrac{ 1 }{ 2 } \cdot \ \dfrac{ 1 }{ 3 } = \dfrac{ 1 }{ 6 } \doteq 0.1667 \ \\ \ \\ x = \dfrac{ a+b }{ 2 } = \dfrac{ 0.05+0.1667 }{ 2 } = \dfrac{ 13 }{ 120 } \doteq 0.1083 = 0.108$ Our examples were largely sent or created by pupils and students themselves.
