Answer:

he have left 4.45 kg

Step-by-step explanation:

= Total salt purchase - salt used on his sidewalk - sales used on the driveway

$= 10 - 1 \frac{3}{4} - 3 \frac{4}{5}\\\\= 10 - \frac{7}{4} - \frac{19}{5}\\\\= \frac{200 - 35 -76 }{20} \\\\= \frac{89}{20}$

= 4.45 kg

Hence, he have left 4.45 kg
