Answer 1

Answer:

Hey Mate!!

Total Number of Parts = 22 + 0.5 + 2.5 = 25

$Percentage\: of\: copper = \frac{22}{25} \times 100 = 22 \times 4 = \boxed{\bold{88\%}}\\\\Percentage\: of\: tin = \frac{2.5}{25} \times 100 = 2.5 \times 4 = \boxed{\bold{10\%}}\\\\Percentage\: of\: copper = \frac{0.5}{25} \times 100 = 0.5 \times 4 = \boxed{\bold{2\%}}$
