Hi. This can be answered with a ratio. If 1 litre = 1 kilogram then 1.75 litres = unknown grams. So we know that there are 1000 grams in 1 kilogram so 1.75 litres would be 1750 grams. Its just a matter of cross multiplying.

Answer:
4.9%
Step-by-step explanation:
6600 * 107/100 = 66*107 = 7062.
3500 * 101/100 = 35x101 = 3535
7062+3535=10597. Original worth: 10100
10597-10100 = 497
497/10100 = 0.0492079208, or 4.92%, rounds to 4.9%
