[\frac{7}{12}  + ( -  \frac{5}{12} )] -[ \frac{5}{9}   + ( -  \frac{2}{9} )] \\  \\  =   [ \frac{7}{12}  -  \frac{5}{12} ] - [ \frac{5}{9}  -  \frac{2}{9} ] \\  \\  = [  \frac{7 - 5}{12} ] -  [  \frac{5 - 2}{9} ] \\  \\  =  \frac{2}{12}  -  \frac{3}{9}  \\  \\  =  \cancel \frac{2}{12}  -  \cancel \frac{3}{9}  \\  \\  =  \frac{1}{6}  -  \frac{1}{3}  \\  \\  =  \frac{1 - 2}{6}  \\  \\  =  - \frac{1}{6}

Answer:

         \frac{-1}{6}

Step-by-step explanation:

Sum \ of \ \ \frac{5}{9} \  and \ \frac{-2}{9} =\frac{5}{9} + \frac{-2}{9} = \frac{5-2}{9} = \frac {3}{9} = \frac{1}{3}

Sum \ of \  \frac{7}{12} \ and \ \frac{-5}{12} = \frac{7}{12} \ + \ \frac{-5}{12} = \frac{7-5}{12} = \frac{2}{12} = \frac{1}{6}

subtract \ first \ from \ second = \frac{1}{6} - \frac{1}{3} = \frac{1 -2}{6} = \frac{-1}{6}

digit at tens place of two digit number is twice the digit at units place .if sum of this number and the no.formed by reversing
Dima020 [189]
Let the number be     xy ,

xy = 10x + y.   when reversed = yx = 10y + x

x = 2y          ........(a)

10x + y + 10y + x = 66.........(b)

10(2y) + y + 10y + 2y = 66

20y + y + 10y + 2y = 66

33y = 66

y = 66/33

y = 2

x = 2y = 2*2 = 4

Recall the original number is xy =     42.
