Answer:
75 %
Explanation:
[ 18÷24=0.75
0.75 x 100 = 75]
The 100 % of gold is 24karat
6 k is 25%
12 k is 50%
18 k is 75 %
24 % is 100 %
24 divided by 6 is 4 x 100 =400
Multiply the whole number by 100. The resulting answer is its value as a percentage. Another way is to add a decimal point after the whole number such as 4, and then move the decimal two spaces to the right, fill in each of those empty spaces with a zero, and add a percentage symbol = 400%
