Answer:
A
Step-by-step explanation:
You first want to simplify the proportions:
7:11 becomes 1:11/7
16:25 becomes 1:25/16
Now you find the LCM of the denominators of the copper which is 112 and that gets us to:
176/112 and 175/112
you see the numerator of the first one is bigger so the number is bigger so the awnser is A
The missing percent is 70
7/10 times 10 is 70/100 which is 70 %
