Enter 2 fractions below:

Estimate the difference to the nearest 1/2

Estimate 3/4 with 1/2 as a benchmark:

Display the fraction bar for 3/4

The range is [1/2, 1]
The halfway point is denoted below:
Therefore, our range is 1/2 < 3/4 < 1

Compare our fraction to the mid point

3/4 ≥ 3/4, we round up to 1

Estimate 1/2 with 1/2 as a benchmark:

Display the fraction bar for 1/2

The range is [0, 1/2]
The halfway point is denoted below:
Therefore, our range is 0 < 1/4 < 1/2

Compare our fraction to the mid point

1/2 ≥ 1/4, we round up to 1/2

Estimating, we have 1 - 1/2

Fraction 1 is a whole number, so convert it based on the Denominator of Fraction 12 multiply top and bottom by 2
