Question

Estimate the difference.

seven-eighths minus six-sevenths

0

one-half

1

one and one-half

Answer 1

I would think you just use the rounding rule on both numbers and then subtract.

To round 7/8 or 6/7, you can compare it to the fraction 1/2 to see if it is greater than or less than 1/2 by doing a cross multiply. If the fraction is greater than 1/2, then round up to one. If the fraction is less than 1/2, round down to zero.

Or you could draw a number line for each fraction to see if the fraction is more than half way. If more than half way round up to one. If less than half way round down to zero.

Anyhow your answer, appears to me zero.
