Question

express 2.57 as fraction in simplest form​

Answer 1

To convert 2.57 to fraction, follow these steps:

First write down the decimal number divided by 1 like this:

2.57
1

As we have 2 digits after the decimal point in the numerator, we need to multiply both the numerator and denominator by 102 = 100, so that there is no decimal point in the numerator

2.57 × 100
1 × 100
=
257
100



As the numerator is greater than the denominator, we have an improper fraction, so we can also express 2.57 as a mixed number, thus 257/100 is equal:

2
57
100
