Mixed numbers

Rewrite mixed numbers so the fractions have the same denominator:

5 1/5 - 2 2/3

Result

x =  2.533

Solution:

a=5 15+1 35 3=7815  b=2 15+2 53 5=4015  x=ab=78154015=784015  x=38152.5333=2.533a=\dfrac{ 5 \cdot \ 15+1 \cdot \ 3 }{ 5 \cdot \ 3 }=\dfrac{ 78 }{ 15 } \ \\ \ \\ b=\dfrac{ 2 \cdot \ 15 + 2 \cdot \ 5 }{ 3 \cdot \ 5 }=\dfrac{ 40 }{ 15 } \ \\ \ \\ x=a-b=\dfrac{ 78 }{ 15 } -\dfrac{ 40 }{ 15 }=\dfrac{ 78-40 }{ 15 } \ \\ \ \\ x=\dfrac{ 38 }{ 15 } \doteq 2.5333=2.533
