Question

the ratio of copper and aluminium in an alloy 8s 3 :5 . if the weight of copper is 12.8 kg in the alloy , find the weight of aluminium in the alloy .​

Answer 1

Answer:

21.34 kg

Step-by-step explanation:

Ratio of copper and aluminium in an alloy = 3 : 5

Weight of copper in the alloy = 12.8 kg

∴ Weight of aluminium in the alloy =  $\frac{3}{5} * \frac{12.8}{y}$

                                                         = $\frac{12.8*5}{3}$

                                                         = 21.34 kg
