Final answer:
To express 0.012 kilograms as a percent of 10 grams, we first convert 0.012 kilograms to grams (12 grams) and then calculate the percent which gives us 120%.
Step-by-step explanation:
To express 0.012 kilograms as a percent of 10 grams, first we need to ensure both quantities are in the same units. Using the fact that 1 kilogram equals 1000 grams, we convert 0.012 kg to grams:
0.012 kg × 1000 g/kg = 12 g.
Now we have 12 grams and we want to find what percent this is of 10 grams. The formula for percent is:
(part / whole) × 100%
So, 12 g is what percent of 10 g?
(12 g / 10 g) × 100% = 120%
Therefore, 0.012 kilogram is 120% of 10 grams.
