Answer:
1) x=0.3 y=2.2
2) x=6 y=9
Explanation:
1/5 is 20% because 100 divided by 5 is 20. So 11 and 1.5 times 0.20 will get the amount for 20% aka 1/5. So 1.5, x, times 0.20 is 0.3. 11, y, times 0.20 is 2.2. For the next problem, 1:3 means that you multiply a side on E by 3 to get that same side on D. So 3, y, times 3 is 9. To get x, you reverse it. So 18, x, divided by 3 is 6.
