\huge \boxed{\mathfrak{Question} \downarrow}


  • \sf \: 3 ( \frac { 3 } { 4 } ) + 4 ( \frac { 1 } { 2 } - \frac { 3 } { 8 } ) + 2 = ? \\


\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}


\sf \: 3 ( \frac { 3 } { 4 } ) + 4 ( \frac { 1 } { 2 } - \frac { 3 } { 8 } ) + 2 \\

  • Express
    \sf3* \left((3)/(4)\right) as a single fraction.


\sf(3* 3)/(4)+4\left((1)/(2)-(3)/(8)\right)+2 \\

  • The least common multiple of 2 and 8 is 8. Convert 1 / 2 and 3 / 8 to fractions with denominator 8.


\sf(9)/(4)+4\left((4)/(8)-(3)/(8)\right)+2 \\

  • Because 4 / 8 and 3 / 8 have the same denominator, subtract them by subtracting their numerators.


\sf(9)/(4)+4* \left((4-3)/(8)\right)+2 \\

  • Subtract 3 from 4 to get 1.


\sf(9)/(4)+4* \left((1)/(8)\right)+2 \\

  • Multiply 4 and 1 / 8 to get 4 / 8.


\sf(9)/(4)+(4)/(8)+2 \\

  • Reduce the fraction 4 / 8 to its lowest terms by extracting and cancelling out 4.


\sf(9)/(4)+(1)/(2)+2 \\

  • The least common multiple of 4 and 2 is 4. Convert 9 / 4 and 1 / 2 to fractions with denominator 4.


\sf(9)/(4)+(2)/(4)+2 \\

  • Because 9 / 4 and 2 / 4 have the same denominator, add them by adding their numerators.


\sf(9+2)/(4)+2 \\

  • Add 9 and 2 to get 11.


\sf(11)/(4)+2 \\

  • Convert 2 to fraction 8 / 4.


\sf(11)/(4)+(8)/(4) \\

  • Add 11 and 8 to get 19.


= \boxed{ \bf (19)/(4)} \\ = \underline{\bf4.75}
