Answer 1

Given:

Shaddin height:

`57\text{ }(3)/(4)`

Cruz height:

`57\text{ }(3)/(4)+5\text{ }(1)/(2)`

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

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

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

`\begin{gathered} (5)/(4)=(4+1)/(4)=(4)/(4)+(1)/(4) \\ =1+(1)/(4) \end{gathered}`

Then, we add 1 to 62:

`\begin{gathered} 62\text{ }(5)/(4)=62+1\text{ }(1)/(4) \\ 63\text{ }(1)/(4)\text{ inches} \end{gathered}`

Answer:

`63\text{ }(1)/(4)\text{ inches}`
