ohaa [14]

Answer:

Mike can make 4 bows

Step-by-step explanation:

Given

$1\ bow = 3\frac{1}{2}\ ft$

$Ribbon = 14\ ft$

Required

Determine the number of bows he can make

To do this, we simply divide the length of the ribbon by length of 1 bow:

i.e.

$Number = Ribbon/1\ bow$

$Number = 14\ ft/3\frac{1}{2}\ ft$

$Number = 14/3\frac{1}{2}$

$Number = 14/\frac{7}{2}$

Convert to *

$Number = 14 * \frac{2}{7}$

$Number = \frac{28}{7}$

$Number = 4$

<em>Hence, Mike can make 4 bows</em>
