Benchmark Fractions Estimate Sum for 1/2 and 5/8 using nearest 1/8

Enter 2 fractions below:

Estimate the sum to the nearest 1/8

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

Display the fraction bar for 1/2

The range is [3/8, 4/8]
The halfway point is denoted below:



Therefore, our range is 3/8 < 7/16 < 4/8

Compare our fraction to the mid point

1/2 ≥ 7/16, we round up to 4/8

Estimate 5/8 with 1/8 as a benchmark:

Display the fraction bar for 5/8

The range is [4/8, 5/8]
The halfway point is denoted below:



Therefore, our range is 4/8 < 9/16 < 5/8

Compare our fraction to the mid point

5/8 ≥ 9/16, we round up to 5/8

Estimating, we have 4/8 + 5/8

Our estimated answer is 9/8
