Question

Subtract the rrciprocal of 5/7 from the additive inverse of -3/4

Answer 1

$reciprocal \: of \: \frac{5}{7} \: is \: \frac{7}{5} \\ \\ additive \: inverse \: of \: \frac{ - 3}{4 \: } is \: \frac{3}{4}$



therefore according to the question




$= \frac{3}{4} - \frac{7}{5} \\ \\ = \frac{5(3) - 4(7)}{20} \\ \\ = \frac{15 - 28}{20} \\ \\ = - \frac{13}{20}$

Answer 2

Answer: Answer will be -13\20

                                     

Step by Step Explanation: Reciprocal of 5\7 is 7\5.

Additive inverse of -3\4 is 3\4

= 3\4 - 7\5

= 5x3 - 4x7\20

= 15-28\20

= -13\20
