Step-by-step explanation:

To convert the decimal 1.21 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

1.21/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

1.21/1

= (1.21 × 100)

(1 × 100)

= 121/100

This fraction is alread reduced, We can't reduce it any further).

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, this 121/100 is also equal to 121/100 or

[tex]1 \ \ \frac{21}{100} [/tex]

when expressed as a mixed number.
