Enter 2 fractions below:

Estimate the sum to the nearest 1/2


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

Display the fraction bar for 2/3

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

2/3 < 3/4, we round down to 1/2

Estimate 3/8 with 1/2 as a benchmark:

Display the fraction bar for 3/8

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

3/8 ≥ 1/4, we round up to 1/2

Estimating, we have 1/2 + 1/2

Our estimated answer is 1
