Math Problem Statement

Complete the factor pair of 18. What number pairs with 2 to make a factor pair?

Solution

The task in the image asks to complete the factor pair of 18.

The first factor pair shown is 1×181 \times 18.

For 2×_2 \times \_, the missing factor would be the result of 18÷2=918 \div 2 = 9.

So, the completed factor pair would be: 2×92 \times 9
