Answer:
$12
Step-by-step explanation:
setting up a proportion and putting 20 of 100 and 60 over x, we multiply 60 and 20 then divide one hundred from both sides leabing. We should have 100/x = 1200/100. Doing this gives us x = 12.
To find the order smallest to largest we need to find the common denominator the find the equivalent fractions and compare.
the LCD is 48 so
5/6 = 40/48
7/12 = 28/48
1/8 = 6/48
5/16 = 15/48
now we can make a direct comparison...
from smallest to largest
1/8, 5/16, 7/12, 5/6
