Awire 4 1/2 feet long is been cut into small pieces of wire each one and 1/4 feet long what is the maximum number of smaller pie
77julia77 [94]

Answer:

3

Step-by-step explanation:

Wire is 4 1/2 feet, or 4.5 feet.

Each smaller wire needs to be 1 1/4 feet, or 1.25 feet.

<em>How many whole 1.25 feet wire can we have from total of 4.5 feet wire?</em>

<em />

Let's divide:

\\frac{4.5}{1.25}=3.6

<em>thus we can have 3 whole "1.25 feet long" wire and fractional amount.</em>

<em />

<em>Hence, maximum number of smaller pieces is 3</em>
