Como puedo poner 2 3/5 en decimal​
Alex73 [517]

When turning a fraction into a decimal, any whole numbers comes before the "." and the fraction will become after the ".".

To make it simple, turn the fraction into a "over 100" fraction to make it easier.

Multiple both numeriator and denominator by a specific number, to turn the denominator into a 100. You must times the numeriator as well since your changing the denominator.

100 / 5 = 20

So now, multiple both sides of the fraction by 20.

3 x 20 = 60

5 x 20 = 100

2 60/100

Now, put the whole number in front of the decimal symbol.

2.___

Now, take the numeriator and put it behind the decimal symbol.

2.60

So, when turning 2 3/5 into a decimal, it is 2.60.
