Question

There are three fences on a ranch measure 15/16 miles 7/8 miles and 7/16 mile which is the best estimate of the total length of all three fences

Answer 1

Alright, lets get started.

The length of first fence = $\frac{15}{16}$

The length of second fence = $\frac{7}{8}$

The length of third fence = $\frac{7}{16}$

Total length of all three fence = $\frac{15}{16}+\frac{7}{8}+\frac{7}{16}$

For adding them, we need to first make common denominator

Total length of all three fence = $\frac{15}{16}+\frac{2*7}{2*8}+\frac{7}{16}$

Total length of all three fence = $\frac{15}{16}+\frac{14}{16}+\frac{7}{16}$

Now we have common denominator, so

Total length of all three fence = $\frac{15+14+7}{16}$

Total length of all three fence = $\frac{36}{16}$

36 and 16 could be simplified with 4, so

Total length of all three fence = $\frac{9}{4}$   :    Answer
