of: (a) pencil to pen (b) pen to pencil (c) pencil to the total cost of pen and pencils​

Answer 1

Answer:

a) pencil to pen=15.50/25.50

=15.50×100/25.50×100

=1550/2550

=0.607

b) pen to pencil=25.50/15.50

=25.50×100/15.50×100

=2550/1550

=1.645

c) pencil to the total cost of pen and pencil

• Total cost of pen and pencil=25.50+15.50=41
• Therefore,15.50/41
• 15.50×100/41×100
• 1550/41
• =37.804
