t. Then check for reasonableness.
2 answers:
To find out do 24 x 9. Think about it like 24 seats in each row. In other words, 24+24+24+24+24+24+24+24+24.
24 x 9 = 216
There are 216 seats in the auditorium.
For the check for reasonableness part, it's 216 seats➗ 9 rows = 24 seats.
9 rows and 24 seats
9 is rounded to 10 and 24 is rounded to 20
Now multiply 10 x 20 = 200
So estimated answer: 200
But 9 x 24 = 216
So the correct answer is really 216
