Step 1

List the length of the wingspan of the five butterflies

$\frac{1}{4}, \frac{1}{4}, 1, \frac{2}{4}, \frac{3}{4}$

Step 2:

The two butterflies with the shortest wingspan has a wing length of $\frac{1}{4}$ inches each.

Step 3:

Total length of the wingspan of the two butterflies with the shortest wingspan

= $=\frac{1}{4} +\frac{1}{4} \\
 = \frac{2}{4}$

Final answer:

= $\frac{2}{4} inch$

1 1/4mi = ft, can someone explain this to me

skelet666 [1.2K]

First off, we'll convert the mixed fraction to "improper" and check about, keeping in mind that, there are 5280 feet in 1mile.

$\bf \stackrel{mixed}{1\frac{1}{4}~mi}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}~mi}\\\\
-------------------------------$

$\bf \begin{array}{ccll}
feet&miles\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
5280&1\\
f&\frac{5}{4}
\end{array}\implies \cfrac{5280}{f}=\cfrac{1}{\quad \frac{5}{4}\quad }\implies \cfrac{5280}{f}=\cfrac{\frac{1}{1}}{\quad \frac{5}{4}\quad }
\\\\\\
\cfrac{5280}{f}=\cfrac{1}{1}\cdot \cfrac{4}{5}\implies \cfrac{5280}{f}=\cfrac{4}{5}\implies \cfrac{5280\cdot 5}{4}=f\implies 6600=f$
