Question

divide the sum of -15/7 and 5/34 by their difference​

Answer 1

Answer:

237/545

Step-by-step explanation:

sum of -15/7 and 5/34  = (-15/7) + (5/34)

                                      = [(-15)(34) + (7)(5)] / [7*34]

                                      = [ - 510 + 35] / 238

                                      = -237/ 238

difference of -15/7 and 5/34  = (-15/7) - (5/34)

                                      = [(-15)(34) - (7)(5)] / [7*34]

                                      = [ - 510 - 35] / 238

                                      = -545/ 238

so, divide the sum by difference

=> (-237/238) ÷ (-545/238)

=> (-237/238) * (-238/545)

=> 237/545
