Question

The ratio of zine and copper in an alloy is 7:9 if the weight of copper in the alloy is 11point7 kg find the weight of zine in it

Answer 1

Answer:

7:9= y:11.7

=y*9 = 7*11.7

= y= 7*11.7/9

= 81.9/ 9

= 9.1

therefore, the weight of zine in the alloy= 9.1 kg

$<b><i><font face=Copper black size=4 color=blue>$ Here is your answer.
Ratio of Zinc : Copper = 7 : 9

Weight of copper is 11.7 kg

Let the weight of the Zinc is x kg

ATQ
$\frac{7}{9} = \frac{x}{11.7} \\ x = \frac{7 \times 11.7}{9} \\ x = 9.1$
Therefore Weight of Zinc is 9.1 kg
