NEED HELP ASAP. I don not understand why I'm wrong. What is the right answer???
hammer [34]

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}
