S= 15
3s=45
3s/3=45/3
S=15
You have to divide both sides
If you are working with time or days, you can't put in a negative value because if you are doing an experiment, you can't go back in time to do that experiment to gather data. (Time for the most part considered to be an input value so that's why I used it as an example.)
If you do 22÷9 and see the hole number: 2. Then do 2 x 9 and you get 18. Now do 22-18 and you get 4. So do 2 4/9. Always have the denominator stay the same.
Answer:
12:40 is the anwser
Step-by-step explanation:
If his flight leaves at 3:15 and it takes and hour and 35 minutes to gett there than you would have to subtract 1 hour and 35 minutes from 3:15 so
3:15 minus 1 hour is 2:15
2:15 minus 35 minutes is 1:40
so now he wants to be and hour and 35 minutes earlier so the anwser would be
2:15 minus 1 hour is 1:15
1:15 minus 35 minutes is 12:40
1 - 2/3 - 1/4
= 1 - 8/12 - 3/12
= 1/12
