Express 4.26 as a mixed number.

Write the decimal number as a fraction
(over 1)
4.26 = 4.26 / 1

Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's

Numerator  = 4.26 × 10 × 10 = 426

Denominator = 1 × 10 × 10 = 100

Numerator / Denominator = 426 / 100

Simplifying our fraction

= 426/100

= 213/50

= 4  13/50
