Answer:
☑ Answer is 6
Step-by-step explanation:
[tex]{ \tt{ \{(8 \times 7) - 2 \} : 9}} \\ = { \tt{(56 - 2) :9 }} \\ = { \tt{54 :9 }}[/tex]
» But this is a ratio, so it can be expressed in terms of fractions:
[tex] = { \tt{ \frac{54}{9} }} \\ [/tex]
» Divide both the denominator and numerator by 9:
[tex]{ \tt{ = \frac{54 \div 9}{9 \div 9} }} \\ \\ = { \tt{ \frac{6}{1} }} \\ \\ = 6[/tex]
