How do you write 25 as decimal?

We can write this as a decimal by making the denominator 10
It is 0.4
Explanation:
The easiest way to write this as a decimal is to multiply it until the denominator is 10. As decimals are written in a tens system (with a tenths, hundredths, thousandths, etc. place), fractions with a denominator of 10 can easily be written as decimals.
The way to make the denominator ten is to multiply both the top and bottom by

\frac{10}{the bottom number}

. In this case:

(\frac{2}{5}) \cdot (\frac{\frac{10}{5}}{\frac{10}{5}})

(\frac{2}{5}) \cdot (\frac{2}{2})

To simplify, we can multiply the two numerators and the two denominators.

\frac{2 \cdot 2}{5 \cdot 2}

When we simplify, we get:

\frac{4}{10}

This, in words, is four tenths. Therefore, we put 4 in the tenths place of the decimal.
In decimal form, this is 0.4

25=410=0.4  Explanation:  Decimals are way of writing fractions which have a power of  10 in the denominator. They will be 10,100,1000,10,000 ,and so on.  In 25 make the denominator  10  25×22=2×25×2=410=0.4  Note that 22=1 and multiplying any number by 1 does not change its value.  However, some fractions have denominators which cannot be made into a power of 10  In that case, divide the numerator by the denominator to get a decimal.  25=2÷5=0.4
