What is 1.25 as a fraction?

1.25 can be expressed as the fraction 5/4.

Here's why:

• Method 1 (using place value): 1.25 means 1 + 2/10 + 5/100. This simplifies to 1 + 25/100. Simplifying 25/100 by dividing both numerator and denominator by 25 gives you 1/4. Therefore, 1.25 = 1 + 1/4 = 5/4.

• Method 2 (removing the decimal): Multiply 1.25 by 100 to get rid of the decimal, resulting in 125. Since you multiplied by 100, you also need to multiply the denominator by 100 (which is implied; 1.25 can be thought of as 125/100). Then simplify the fraction 125/100 by dividing both numerator and denominator by 25 to get 5/4.
