Question

There are a few crayons missing from the box. Look at the image below and identify the set of equations that represents the missing number of crayons.

Answer 1

Number of crayons still in the box \(= 11\)
Number of crayons missing \(= 9\)
Total number of crayons \(= 11 + 9 or 9 + 11\)



Therefore, the total number of crayons is \(20\).

The related subtraction equations framed are \(20 – 11 = 9\) or \(20 – 9 = 11\).

Hence, Option C is correct, and the equations are \(11 + 9 = 20\) and \(20 – 11 = 9\).
