Suppose that Sahil knows that 45 people with ages of 18 to 29 voted. Without using a calculator, he quickly says then 135 people with ages of 30 to 49 voted. Is he correct? how might Sahil have come up with his answer so quickly?
His answer is correct because if you have the pie chart, it shows the percentage. he did 45 times 3 to get the 135 because he though since 10% is 45 people he could multiply by 3 & get his answer. Hope this helped.
