Question

Porportions

6/7 over 5 equals 10/7 over 3

Answer 1

(6/7)/5 = ?
(10/7)/3 = ?

Evaluate: (6/7)/5 = 6/(7*5) = 6/35

(10/7)/3 = ?

Answer 2

\[\Huge \frac{ \left( \frac{ 6 }{ 7} \right) }{5 }=\frac{ \left( \frac{ 10 }{ 7 } \right)}{ 3 }\]
is this your problem?

That would simplify to \[\Large \frac{ 6 }{ 35 } = \frac{ 10 }{ 21 }\] which are not equal.
