Find LCD on top and add the fractions.
Flip division into multiplication.
$13/200$

$(4/5 + 2/4)/20$

work the numerator by finding a common LCD so we can make it one term
$4/5 + 2/4 = 4/5 + 1/2$

$4/5 + 1/2" "$ LCD is $10 = 5*2$

$((4*2)/(5*2) + (1*5)/(2*5))/20$

$8/10 + 5/10 = 13/10$

$(13/10)/20$ which means $13/10 div 20$

inverse of division is multiplication

inverse of 20 is $1/20$ because $20/1 * 1/20 = 1$

$13/10 * 1/20$

$= 13/200$
