Question 713342
It follows the meaning of multiplication.


{{{4x(3/5)=(3/5)+(3/5)+(3/5)+(3/5)}}}, and because the denominators are all 5,
={{{(3+3+3+3)/5}}}, and again using the meaning of multiplication, we can express as:
{{{4x3/5}}}



In slightly more advanced levels of Arithmetic, we do not use an "x" to indicate the multiplication operator.  We may rather use a mid-level dot this way:
{{{4*3/5}}},  the {{{4*3}}} being 4 multiplied by 3.  Another common alternative is the put each regular number into separate grouping symbols.  {{{(3)(4)}}} would mean, 3 multiplied by 4.
