Question

extrusion, alloys, and ratios
an aluminum alloy is being used to extrude pipes for a submarine. the composition of

• aluminum (al): 93 percent
• manganese (mn): 4 percent
• silicon (si):?

calculate the ratio of aluminum, manganese, and silicon in the alloy. this ratio will be
following order: al : mn : si.
al : mn : si
93 : 4 : 2
93 : 2 : 5
93 : 3 : 4
93 : 4 : 3
submit answer

Explanation:

Step1: Calculate silicon percentage

Since the total percentage of components in an alloy is 100%, and aluminum is 93% and manganese is 4%. So the percentage of silicon is $100 - 93 - 4=3$%.

Step2: Determine the ratio

The ratio of aluminum : manganese : silicon is based on their percentages, so it is $93:4:3$.

Answer:

93 : 4 : 3
