Questions like this ("how much higher is x than y?") are answered by computing the ratio of the two quantities.
In fact, for example, the answer to "how much higher is 10 than 5?" is 2, because 10:5 = 2, and indeed 10 is twice as much as 5.

, 71.4% of the weight of the bar is silver.
D = 0.32
d - 8 / 5 = -4d
d - 1.6 = -4d
d + 4d = 1.6
5d = 1.6
d = 0.32
This is an exact question in my math textbook. It should be correct.
