A theater has 1500 seats. One night, 9 out of 10 seats were filled. How many people attended that night?

1350

9660962531

To find out how many people attended that night, we can use the following steps:

Step 1: Calculate the total number of seats filled.
Number of seats filled = (9/10) * Total number of seats
Number of seats filled = (9/10) * 1500

Step 2: Calculate the number of people who attended.
Number of people who attended = Number of seats filled

Therefore, the number of people who attended that night is:
Number of people who attended = (9/10) * 1500

To find the number of people who attended the theater that night, you need to calculate 9/10 of the total number of seats.

First, calculate 9/10 of 1500 using the following steps:

Step 1: Write the fraction 9/10 as a decimal by dividing the numerator (9) by the denominator (10):

9 ÷ 10 = 0.9

Step 2: Multiply the decimal by the total number of seats:

0.9 × 1500 = 1350

Therefore, 1350 people attended the theater that night.
