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

  • Simplify \huge \sf\frac { \frac { 3 } { 4 } - \frac { 5 } { 2 } } { \frac { 3 } { 5 } - \frac { 3 } { 2 } } \\

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

\huge \sf\frac { \frac { 3 } { 4 } - \frac { 5 } { 2 } } { \frac { 3 } { 5 } - \frac { 3 } { 2 } } \\

  • The least common multiple of 4 and 2 is 4. Convert \sf\frac{3}{4}and \sf\frac{5}{2}to fractions with denominator 4.

\huge \sf \frac{\frac{3}{4}-\frac{10}{4}}{\frac{3}{5}-\frac{3}{2}}  \\

  • Because \sf\frac{3}{4}and \sf \frac{10}{4} have the same denominator, subtract them by subtracting their numerators.

\huge \sf\frac{\frac{3-10}{4}}{\frac{3}{5}-\frac{3}{2}}  \\

  • Subtract 10 from 3 to get -7.

\huge \sf\frac{-\frac{7}{4}}{\frac{3}{5}-\frac{3}{2}}  \\

  • The least common multiple of 5 and 2 is 10. Convert \sf\frac{3}{5} and \sf \frac{3}{2} to fractions with denominator 10.

\huge \sf\frac{-\frac{7}{4}}{\frac{6}{10}-\frac{15}{10}}  \\

  • Because \sf \frac{6}{10} and \sf \frac{15}{10} have the same denominator, subtract them by subtracting their numerators.

\huge \sf\frac{-\frac{7}{4}}{\frac{6-15}{10}}  \\

  • Subtract 15 from 6 to get -9.

\huge \sf\frac{-\frac{7}{4}}{-\frac{9}{10}}  \\

  • Divide \sf-\frac{7}{4} by \sf-\frac{9}{10} by multiplying \sf-\frac{7}{4} by the reciprocal of \sf-\frac{9}{10}.

\huge \sf-\frac{7}{4}\left(-\frac{10}{9}\right)

  • Multiply \sf-\frac{7}{4} by \sf-\frac{10}{9} by multiplying the numerator by the numerator and the denominator by the denominator.

\huge \sf\frac{-7\left(-10\right)}{4\times 9}

  • Carry out the multiplications in the fraction \sf\frac{-7\left(-10\right)}{4\times 9}.

\huge \sf\frac{70}{36}

  • Reduce the fraction \sf\frac{70}{36} to its lowest terms by extracting and cancelling out 2.

\huge \boxed{ \bf\frac{35}{18}\approx 1.944..}

Answer:

<u>Answer</u><u>:</u><u> </u><u>3</u><u>5</u><u>/</u><u>1</u><u>8</u>

Step-by-step explanation:

\frac{ \{ \frac{3}{4} -  \frac{5}{2}  \} }{ \{ \frac{3}{5}  -  \frac{3}{2}  \}}   =  \frac{( -  \frac{7}{4} )}{ (-  \frac{9}{10} )}  \\  \\   =  \frac{7}{4}  \div  \frac{9}{10}

use the reciprocal of 9/10 :

=  \frac{7}{4}  \times  \frac{10}{9}  \\  \\  =  \frac{35}{18}
