To improper fraction

Change mixed number to improper fraction

a) 1 2/15

b) -2 15/17

Result

a =  1.133
b =  -2.882

Solution:

a=1+215=1715≐1.1333=1.133a = 1 + \dfrac{ 2 }{ 15 } = \dfrac{ 17 }{ 15 } \doteq 1.1333 = 1.133
b=−(2+1517)=−4917≐−2.8824=−2.882b = -(2 + \dfrac{ 15 }{ 17 } ) = - \dfrac{ 49 }{ 17 } \doteq -2.8824 = -2.882
