16/20 = 8(2)/10(2) = 8/10. 8/10 can also be further reduced to 4/5.
15/3 - 14/2
This is the expression you are looking for

Answer:
1:10pm
Step-by-step explanation:
1st, you add all the time needed to make the chili & cook it.
1 hour + 10 minutes + 1 hour + 40 minutes = 2 hours & 50 minutes.
Now you work backwards from 4:00pm.
You go back 2 hours & you would be at 2:00pm
Now you go back another 50 minutes & you would be at 1:10pm
To double check, you can add 2 hours & 50 minutes to 1:10pm & you would get 4:00pm
24.9/150* 100%= 16.6%
16.6% of 150 is equal to 24.9~
