Answer:
I will show you an example. The number at the right side is denominator, the left side is numerator.
Example 1:
24/48
How to make it to the simply number?
24/48 ÷ 24 = 1/2
Example 2:
24/40 and 18/30
How to see if the last simply number is same?
24 can divide: 1, 2, 3, 4, 6, 8
40 can divide: 1, 2, 4, 5, 8, 10
The same number that they can divide is 4 and 8
I choose 4, 24 ÷ 4 = 6, 40 ÷ 4 = 10
6/10
Can it be more simply?
Yes
6 and 10 still can divide 2
6 ÷ 2 = 3
10 ÷ 2 = 5
3/5
It was hard to explain more in here
I will have a meeting at 2:00 Tomorrow, I will tell you more, and show you the notes that my teacher gave.
