Division

99 ÷ 9 = 11

• Count the rows, then count how many are in each row: 9 rows of 11 makes 9 × 11 = 99.
• As repeated addition that is 11 added 9 times: 11 + 11 + 11 + 11 + 11 + 11 + … = 99.
• Turning the array on its side does not change the total, which is the commutative property: 9 × 11 = 11 × 9 = 99.
• The same picture shows the two division facts as well: 99 ÷ 9 = 11 and 99 ÷ 11 = 9.
