Question

which equation can be used to verify that 99 ÷ 11 = 9?
○ 99 - 11 = 88
○ 99 × 9 = 891
○ 9 × 11 = 99

Explanation:

Step1: Recall division verification rule

To verify a division \( a \div b = c \), we use \( c \times b = a \).

Step2: Apply to \( 99 \div 11 = 9 \)

Here, \( a = 99 \), \( b = 11 \), \( c = 9 \). So the verification equation is \( 9 \times 11 = 99 \).

Answer:

\( 9 \times 11 = 99 \) (the third option in the list)
