The expected number of left-handed people in the sample= 45

<h3>Calculation of total number of left-handed</h3>

The number of people selected at random= 450

The percentage of people that are left-handed =10%

= 4500/100

Compare the two ratios by entering &gt;, &lt; , or = in the box.<br> ​ 1/8 ​ 3/20 ​
Elanso [62]
In order to compare the fractions, we need to convert them into decimal form, 
1/8 = 0.125
3/20 = 0.15
As 0.15 > 0.125

In short, Your Answer would be 3/20 > 1/8

Hope this helps!
