prisoha [69]

Answer:

3,000

Step-by-step explanation:

Basically, there are 300 seats filled which is 10%

100% is 10x10

300=10%

multiply both sides by 10

300x10=3000 and 10x10=100

therefore, the total number of seats is 3000 since 100% represents the whole thing.

Hope this was helpful!

The area rug is 4 15/32 square meters. The rug is 2 3/4 meters in length. How wide is the rug
Whitepunk [10]
Steps:
1. To do this problem, you have to divide the area by the length
