0.83 as a fraction

0.83 = 83/100.

Said aloud, this is the same phrase as a different number. Here the repeating block is 3 in one reading and 0.83 in the other, so the answers differ: 0.83 is 83/100, while 0.8(3) is 5/6. Which one you meant depends on where the bar sits over the digits.

How it gets there

  1. Put the digits over their place value. 0.83 has 2 decimal places, so it is 83/100.
  2. Nothing divides both. 83 and 100 share no factor greater than one, so 83/100 is already in lowest terms — which is why this one looks like it has not been simplified.

Questions people actually ask

What is half of 0.83?

What is 0.83 as a fraction?
83/100, in lowest terms. 83/100 is the same value before reducing, and dividing both by 1 gets there.
How do you convert 0.83 to a fraction step by step?

Work it out for any decimal

The two calculators this page is built from take any numbers you like: reduce a fraction shows the divisor it used, and fraction to decimal goes the other way, to the nearest 16th, 32nd and 64th.
