Here , we have been asked to find sum of the expression
[tex] 4 yd. 8 in. + 6 yd. 6 in [/tex]
Here we have two different units , so we will convert it to one after adding
[tex] 4 yd. 8 in. + 6 yd. 6 in=10yd.14in.\\
\\
\text{As we know that }1in=0.0277778yd\\
\\
\Rightarrow 14in=0.388889yd\\
\\
\text{Hence we can write }\\
\\
4 yd. 8 in. + 6 yd. 6 in=10yd.14in.=10.388889yd\\
\\
\text{After rounding we have}\\
\\
4 yd. 8 in. + 6 yd. 6 in=10.39yd [/tex]
