Hi angelangelina,
I'm assuming what you're asking is if you take any two numbers from 1 - 10, and divide them, which pairs will give you a whole number.
First off, all numbers divided by themselves will return 1, so 1/1, 2/2, 3/3, and so on up to 10/10.
Next, with 4 as the numerator (2 and 3 are what are called prime numbers, so only dividing by 1 will give you a whole number), 4/2 will give you 2.
Next, with 6 as the numerator (5 is also prime), 6/2 will give you 3 and 6/3 will give you 2.
Next, with 8 (7 is also prime), 8/2 will give you 4 and 8/4 will give you 2.
Next with 9, 9/3 will give you 3.
Next, with 10, 10/2 = 5, and 10/5 = 2.
So to answer your question, the fractions of two numbers that can be written as not a fraction but a whole number are:
1/1, 2/2, 3/3, 4/4, 5/5, 6/6, 7/7, 8/8, 9/9, 10/10, 4/2, 6/2, 6/3, 8/2, 8/4, 9/3, 10/2, 10/5.
If you have any further questions, please feel free to message me!
Sincerely, taeuknam.
