now, there are 3 feet in 1 yard, so in 156 feet there are 156/3 or 52 yards.
how many times does 7/8 go into 52? let's check.
[tex]\bf \cfrac{52}{\frac{7}{8}}\implies \cfrac{\frac{52}{1}}{\frac{7}{8}}\implies \cfrac{52}{1}\cdot \cfrac{8}{7}\implies \cfrac{52\cdot 8}{1\cdot 7}\implies \cfrac{416}{7}
\\\\\\
\textit{7 goes into 416 \underline{59 times}, with a \underline{remainder of 3}}\implies 59\frac{3}{7}[/tex]
