To find which expression pair has the same quotient, we need to calculate the quotients of each pair:
-
For the first pair:
\( 9000 ÷ 90 = 100 \)
\( 900 ÷ 90 = 10 \)
(Not the same) -
For the second pair:
\( 9000 ÷ 90 = 100 \)
\( 9000 ÷ 9 = 1000 \)
(Not the same) -
For the third pair:
\( 9000 ÷ 90 = 100 \)
\( 900 ÷ 9 = 100 \)
(Same!) -
For the fourth pair:
\( 9000 ÷ 90 = 100 \)
\( 90 ÷ 9 = 10 \)
(Not the same)
The pair that has the same quotient is 9000 ÷ 90, 900 ÷ 9.
