Question

Simplify :
11/12 ÷( 2/3 + 7/9)

Answer 1

find the common denominator of 2/3 and 7/9 which is 9 so yay it's easy. multiply 2/3 by three and that leaves us with 6/9. now you can add the two terms and you would get \[\frac{ 6+7 }{ 9 }=\frac{ 13 }{ 9 }\]

Answer 2

now to finish this you can divide \[\frac{ \frac{ 11 }{ 12 } }{ \frac{ 13 }{ 9 } }\]
or you can multiply instead by using the reciprocal of 13/9 which is just 9/13
\[\frac{ 11 }{ 12 }*\frac{ 9 }{ 13 }=?\] that would be simplifying it entirely.

Answer 3

1089/156

Answer 4

\[\frac{ 11*9 }{ 12*13 }\]
sorry for the delay.
the answer is \[\frac{ 99 }{ 156 }\]
