move decimal point to the right and divide it by 100
2.58 = 258/100 = 129/50 or 2 29/50 answer//

Decimal positions are 1/10, 1/100, 1/1000 etc. 2.58 extends two digits past the decimal point, so the correct denominator is 100.
2.58 = 258 / 100
To put the fraction in simplest form, check whether the numerator and denominator share any factors.
The only prime factors of 100 are 2 and 5. 258 is clearly not a multiple of 5, but it is a multiple of 2. So divide both numerator and denominator by 2:
258 / 100 = 129 / 50

I would multiply .58 x to equal an integer
The integer easiest is 58
.58 x 100 = 58
Then divide both sides by 100
0.58 = 58/100
2.58 = 258/100

Since the '.58' moiety has two decimal places then we place the decimal over 100 ( 2 zeroes)
Hence
2 .58 = 2 58/100
Cancel down the fraction by '2'
2 29/50 is the fraction.

Every number IS already a fraction we just don't normally put the 1 in the denominator (especially if it has a decimal point)
2.58/1
keep multiplying by 10/10 until no decimal in numerator
2.58/1
25.8/10
258/100
Now we can reduce by removing like factors. If both even, I usually divide by 2/2 first.
258/100
129/50
Cannot reduce further

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are 2 numbers to the right of the decimal point, place the decimal number over 2 (100)Next, add the whole number to the left of the decimal.

2.58 = 258/100
Divide by 2 since both numerator and denominator are even. 129/50
129 can be divided further by 1, 3, 43, 129.
50 can be further divided by 1, 2, 5, 10, 25, 50.
Those 2 don’t share anything in common so 129/50 is in reduced form.
