You are building identical displays for the school fair using 65 blue boxes and 91 yellow boxes. What is the greatest number of
KiRa [710]

Answer:

The greatest number of displays that can be built using all the boxes are 13

(Using 5 blue boxes and 7 yellow boxes for each display).

Step-by-step explanation:

In order to answer the question, the first step is to divide the number of blue boxes and yellow boxes and look for a common ratio ⇒

\frac{65}{91}=\frac{5}{7}

This means that we have a ratio 5:7 for blue boxes and yellow boxes.

We find that each display will have 5 blue boxes and 7 yellow boxes.

To find the greatest number of displays that can be built we can do the following calculation

\frac{65}{5}=13

Or

\frac{91}{7}=13

(We can divide the number of blue boxes by its correspond ratio number or the number of yellow boxes by its correspond ratio number)

In each cases the result is 13 displays.

The answer is 13 identical displays
