Answer:
Frederico raised the most money.
Step-by-step explanation:
Given:
Lewis, Marissa, and Frederico are raising money for school trip.
Lewis race 6/7 of the total amount needed.
Marissa has raised 5/9 of the total amount needed.
Frederico raised 11/10 of the total amount needed.
Question asked:
Who raised the most money ?
Solution:
Lewis raised = [tex]\frac{6}{7}[/tex]
Marissa raised = [tex]\frac{5}{9}[/tex]
Frederico raised = [tex]\frac{11}{10}[/tex]
First of all we will equalize all of the denominator to compare in a easy way.
Took LCM of 7 , 9 and 10, we got 630 as LCM
Now, we will put all of the denominator as 630 as :-
Lewis raised = [tex]\frac{6\times90}{7\times90}=\frac{540}{630}[/tex]
Marissa raised = [tex]\frac{5\times70}{9\times70}=\frac{350}{630}[/tex]
Frederico raised = [tex]\frac{11\times63}{10\times63}=\frac{693}{630}[/tex]
We found that Frederico raised the most money.
