------------------------------------------------ Bob and Ed were given a list of customers to call today. Bob called [tex]\frac{4}{7}[/tex] of the people on the list, and Ed called [tex]\frac{3}{10}[/tex] of the people. How much more of the list did Bob call than Ed?

Use the cross multiply method. Simplify your answer if possible.

To find out how much more of the list Bob called than Ed, we need to compare the fractions [tex]\(\frac{4}{7}\)[/tex] and [tex]\(\frac{3}{10}\)[/tex]. Here's how you can find out the difference:

1. Find a Common Denominator:
The first step is to convert both fractions to have a common denominator, which can be done using cross-multiplication. Here, the common denominator is [tex]\(7 \times 10 = 70\)[/tex].

2. Convert Each Fraction:
- Convert Bob's fraction [tex]\(\frac{4}{7}\)[/tex] to have a denominator of 70:
[tex]\[
\frac{4}{7} \times \frac{10}{10} = \frac{40}{70}
\][/tex]
- Convert Ed's fraction [tex]\(\frac{3}{10}\)[/tex] to have a denominator of 70:
[tex]\[
\frac{3}{10} \times \frac{7}{7} = \frac{21}{70}
\][/tex]

3. Calculate the Difference:
Now, subtract Ed's fraction from Bob's fraction to find the difference:
[tex]\[
\frac{40}{70} - \frac{21}{70} = \frac{19}{70}
\][/tex]

4. Interpret the Result:
The difference, [tex]\(\frac{19}{70}\)[/tex], represents how much more of the list Bob called compared to Ed.

Therefore, Bob called [tex]\(\frac{19}{70}\)[/tex] more of the list than Ed.
