Multiply the denominator ( bottom number) by a number, to make it 10,100 or any 1 followed by zeros.
Then multiply that same number by the numerator ( top number)
[tex]\frac{1}{4}\times\frac{25}{25}=\frac{25}{100}[/tex]Then, write down 25 with the decimal point 2 spaces from the right ( because 100 has 2 zeros)
0.25
