Answer: 6.3 g
Step-by-step explanation:
First, we need to put every mesure into the same unit. Let's put all into grams.
- kg would be too heavy for a quarter (consider that we use kg to weight people, for example)
- mg is too light (consider that we use mg to weight pills, for example)
We know that
1 kg = 1000 g
1 g = 1000 mg
630 g = 630 g
63 mg = 63/1000 = 0.063 g
6.3 g = 6.3 g
0.63 kg = 0.63*1000 = 630 g
The most suitable answer for a quarter is 6.3g, because 630 g would be too heavy and 0.063 g would be too light.
