Question

in a metal alloy the ratio of zinc to Copper is 3 to 14 if there are 450 2 lb of copper how much is zinc is there

Answer 1

we have

ratio is 3:14

Let

x ----->pounds of zinc

y ----> pounds of copper

we have

x/y=3/14

x=(3/14)y -----> equation A

we have

y=450.2 lb

substitute in equation A

x=(3/14)*450.2

x=96.5 lbs

the answer is

96.5 lbs of zinc
