Answer 1

Frederico raised the most money.

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 =
`(6)/(7)`

Marissa raised =
`(5)/(9)`

Frederico raised =
`(11)/(10)`

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 =
`(6*90)/(7*90)=(540)/(630)`

Marissa raised =
`(5*70)/(9*70)=(350)/(630)`

Frederico raised =
`(11*63)/(10*63)=(693)/(630)`

We found that Frederico raised the most money.
