Answer 2

Answer:

$- \frac{37}{4}$

Step-by-step explanation:

$9 - \frac{21}{2} - \frac{31}{4}$

=$9( ( -\frac{21}{2} )+ ( - \frac{31}{4}) )$

=$9(( - \frac{ 21 \times 2}{2 \times2} ) + ( - \frac{ 31 \times 1}{4 \times 1} )$

=$9( - \frac{42}{4} ) + ( - \frac{ 31}{4} )$

=$9 - \frac{73}{4}$

=$\frac{9 \times4 }{1 \times 4} - \frac{73 \times 1}{4 \times 1}$

=$\frac{36}{4} - \frac{73}{4}$

=$\frac{ - 37}{4}$
