Use associative property to multiply 2-digit numbers by 1-digit

Let's use the associative property to help us solve

27 \times 2

Complete the equations by breaking $27$ ‍ into two smaller factors.


$27 \times 2 =$ ‍	$\times 2$ ‍
$27 \times 2 =$ ‍	$9 \times$ ‍ Your answer should be an integer, like $6$ ‍ a simplified proper fraction, like $3 / 5$ ‍ a simplified improper fraction, like $7 / 4$ ‍ a mixed number, like $1 3 / 4$ ‍ an exact decimal, like $0.75$ ‍ a multiple of pi, like $12 pi$ ‍ or $2 / 3 pi$ ‍
