how would I make 2.0 into a fraction

It really just depends.

It could be a lot of differen things:
4/2, 6/3, 8/4, e.t.c

It just depends on what you want to make it compatible with. For example, say you had 2 + (7/8).
You would need to put that 2 into a fraction with a denominator of 8. You would multiply 2 by 8 and have 16/8.
Then you'd have:
(16/8) + (7/8), add your numerators and get 23/8.

To convert a decimal number like 2.0 into a fraction, you need to consider the place value of the decimal. In this case, 2.0 is equivalent to the integer 2.

To express 2.0 as a fraction, you can write it as 2/1. The numerator (top number) represents the value of the decimal, and the denominator (bottom number) represents the place value.

Therefore, 2.0 as a fraction would be written as 2/1.
