$\frac{153}{50}$ $153/50$

$0.3 y + \frac{y}{z}$ $0.3y + y/z$

$\frac{3}{10} y + \frac{y}{z}$ $3/10y + y/z$

When;

$y = 10 and z = 5$ $y = 10 and z = 5$

Plugging the values into the equation;

$\frac{3}{10} (10) + \frac{\frac{3}{10}}{5}$ $3/10(10) + (3/10)/5$

$3/cancel10cancel(10) + (3/10)/5$

$3 + (3/10)/5$

$3 + 3/10 div 5$

$3 + 3/10 xx 1/5 ->"transposed"$

$3 + 3/50$

Taking LCM

$(150 + 3)/50$

$153/50$
