List the ratio in simplest form, without labels. Enter your answer with colon (e.g. 1:1)____PART BWhat percent of each order will be size medium items?____

Answer :

Part A)

To find the ratio, find the total amount of items and the tota amount of medium size items by adding the numbers of the columns:

[tex]\begin{gathered} \text{Total number of ordered items }=40+60+80 \\ =180 \end{gathered}[/tex][tex]\begin{gathered} \text{Total medium size items }=10+15+20 \\ =45 \end{gathered}[/tex]

Next, divide the total amount of medium size items by the total amount of items and simplify the fraction:

[tex]\frac{45}{180}=\frac{1}{4}[/tex]

Therefore, the ratio is 1:4.

Part B)

To find the percentage, write the ratio in a decimal representation and multiply it by 100:

[tex]\begin{gathered} \frac{1}{4}=0.25 \\ 0.25\cdot100=25 \end{gathered}[/tex]

Therefore, 25% of each order will be size medium items.
