Answer

$6+\frac{3}{10}-1 \frac{8}{15} $
$=\frac{6}{1}+\frac{3}{10}-\frac{23}{15} $
$=\frac{6 \times 30}{1 \times 3}+\frac{3 \times 3}{10 \times 3}-\frac{23 \times 2}{15 \times 2} \ldots \ldots . .(\text { LCM of } 1,10,15=30) $
$=\frac{180}{30}+\frac{9}{30}-\frac{46}{30} $
$=\frac{180+9-46}{30}=\frac{189-46}{30} $
$=\frac{143}{30}=4 \frac{23}{30}$
