Answer: 1: 10/1
2: 12/3
The question is asking if you can do 20 push-ups in 2 minutes how many can you do in 1
To make the 2 a 1 divide by 2. Rennet with fractions you have to do the same thing you did on the bottom on the top.
For example
We would have to divide 20 by 2 because we divide 2 by 2.
So 20 divide by 2 is 10
Now we have 10/1 as our answer
Now we have to do the same thing but they have us different information do it might be a little different.
36/9 = 12/?
Now we just have to work backwards.
How do you get 36 to 12?
You divide by 3
36 divided by 3 = 12
Remember whatever we do to the top we have to do to the bottom
9 divided by 3 = 3
So you get 12/3
Hope this helps and makes sense
