Answer:

☑ Answer is 6

Explanation:

${ \tt{ \{(8 * 7) - 2 \} : 9}} \\ = { \tt{(56 - 2) :9 }} \\ = { \tt{54 :9 }}$

» But this is a ratio, so it can be expressed in terms of fractions:

$= { \tt{ (54)/(9) }} \\$

» Divide both the denominator and numerator by 9:

${ \tt{ = (54 / 9)/(9 / 9) }} \\ \\ = { \tt{ (6)/(1) }} \\ \\ = 6$
