Two different types of brass coating Copper and Zinc in the ratio of measurement 8:3 and 15:7 respectively. Let’s work out what the ratio of measurement of Copper and Zinc will be if these two types of brass are mixed together in the ratio of measurement 5:2.

Answer :

Ratio of copper and zinc in first type of brass = 8:3


Ratio of copper and zinc in second type of brass = 15:7


So,


Ratio of copper in first type of brass


These two types of brass are mixed together in the ratio of measurement 5:2


First type brass copper in new ratio 5:2


Ratio of copper in second type of brass


Second type brass copper in new ratio


ratio of zinc in first type of brass


first brass zinc in new ratio 5:2


second type zinc in new ratio


so, ratio of copper to zinc in new ratio 5:2








ratio of copper to zinc in new ratio 5:2 = 5:2
