Answer:

6. 184.275 gr

7. 72 km

8. 368000 cm

Explanation:

To make these conversions, we need to know the following relationships:

1 ounce = 28.35 gr

1 mile = 1.6 km

1 km = 100000 cm

Then, we can convert each expression as follows:

6.5 oz x 28.35gr / 1 oz = 184.275 gr

45 mi x 1.6 km / 1 mi = 72 km

2.3 mi x 1.6 km/ 1 mi = 3.68 km x 100000 cm/ 1km = 368000 cm

Therefore, the answers are:

6. 184.275 gr

7. 72 km

8. 368000 cm
