Question

Estimate the following difference by replacing each with 0,1/2 or 1

Answer 1

We need to replace the fractions buy 0, 1/2 or 1 and estimate the difference of:

`(7)/(8)-(6)/(11)\approx1-(1)/(2)=(1)/(2)`

We can replace 7/8 by 1 because is the nearest number, and 6/11 by 1/2 for the same reason.
