\(\frac { 3 }{ 8 }\) times \(\frac { 4 }{ 9 }\) ,
\(\frac { 3 }{ 8 } \cdot \frac { 4 }{ 9 } =\frac { 12 }{ 72 }\)
3 groups of 4/9 means , 3 times 4/9
\(3\cdot \frac { 4 }{ 9 } =\frac { 3\cdot 4 }{ 9 } =\frac { 12 }{ 9 }\)
Now let's divide this divide by 8.
\(\frac { \frac { 12 }{ 9 } }{ 8 } =\frac { 12 }{ 9 } \cdot \frac { 1 }{ 8 } =\frac { 12\cdot 1 }{ 9\cdot 8 } =\frac { 12 }{ 72 }\)
As you can see when we divided 3 groups of 4/9 we got the same result as 3/8 x 4/9
