Answer 1

Given:

Shaddin height:

$57\text{ }\frac{3}{4}$

Cruz height:

$57\text{ }\frac{3}{4}+5\text{ }\frac{1}{2}$

To find Cruz height, add the integer parts and the fraction:

$\begin{gathered} (57+5)(\frac{3}{4}+\frac{1}{2}) \\ 62(\frac{3}{4}+\frac{1}{2}) \\ 62(\frac{3+2*1}{4}) \\ 62\text{ }\frac{5}{4} \end{gathered}$

Now, we have to transform 5/4, since the numerator must be lower than the denominator.

$\begin{gathered} \frac{5}{4}=\frac{4+1}{4}=\frac{4}{4}+\frac{1}{4} \\ =1+\frac{1}{4} \end{gathered}$

Then, we add 1 to 62:

$\begin{gathered} 62\text{ }\frac{5}{4}=62+1\text{ }\frac{1}{4} \\ 63\text{ }\frac{1}{4}\text{ inches} \end{gathered}$

Answer:

$63\text{ }\frac{1}{4}\text{ inches}$
