Question

On Planet Z, the aliens use the following conversions: 1 zorg = 3 blags 5 blags = 2 trogs 8 trogs = 1 drobe. So, 9 drobes equals how many zorgs?

Answer 1

Answer:

9 drobes= 60 zorgs

Step-by-step explanation:

we have

1 zorg= 3 blags

5 blags=2 trogs

8 trogs= 1 drobe

Now

1 drobe = 8 trogs

= 8 ((5/2) blags)

= 20( blags )

= 20((1/3)zorg)

= (20/3)zorg

so 1 drobe= 20/3 zorg

Therefore 9 drobes=( 9× 20/3) zorg )

9 drobes= 60zorg
