# How do you write 4.01 as a fraction?

You can eliminate the decimal point by multiplying by 100. You can keep the same value you started with by dividing that result by 100.   4.01 = (4.01*100)/100 = 401/100
Any decimal is easily converted to a fraction this way. Remove the decimal point and express the resulting value over 1 followed by the number of zeros formerly to the right of the decimal point. Example with 1 decimal place: 0.1 = 01/10 Example with 3 decimal places: 84.323 = 84323/1000  Then, you can reduce the fraction by dividing out the factors of 2 or 5 that may exist.   1.25 = 125/100   = 25/20    both numerator and denominator divided by 5   = 5/4    both numerator and denominator divided by 5 again.

Set 4 aside. Put .01 over 1

.01/1

move decimal places all the way right, top and bottom, to whole numbers

1/100

now

4 and 1/100

change to improper fraction

(100*4+1)/100

= 401/100
------that is how you get the answer you already have
