To solve this, you must follow PEMDAS. First, solve the parenthesis. Because a negative times a positive equals a negative, the product of the fractions is -1/6. Then multiply that by 12. That equals -12/6. This can be simplified down to -2.

Let there are x glass figurinesin room. as museum decided to showcase in total 9 different room as total number of glass figurines are:

Determine the number of glass figurines in 7 rooms.

The total collections is of 9x glass figurines.
In 7 rooms the collections appear is 7x.
Determine the fraction of collection that will appear in 7 rooms.

So, the answer is 7/9.
It is 5.125 (although idk if u have to make it in fraction form)
Answer:
