Complete Question
10) The Taylors have four dogs. Molly eats 4 1/2 cups of food each day. Roscoe eats 3 2/3 cups. Milo eats 1 3/4 cups, and Fifi eats 3/4 cups.
The vet told the Taylors( from problem 10) to reduce the amount Molly eats by 3/4 cups.
a) After Molly's food is adjusted will she eat more or less than Roscoe each day?
b) how much more or less
Answer:
a) After Molly's food is adjusted will she eat more or less than Roscoe each day?
Molly eats more than Roscoe each day
b) how much more or less?
Molly eats more than Roscoe by 1/12 cups
Step-by-step explanation:
We are told in Problem 10 that :
Molly eats 4 1/2 cups of food each day.
The vet said to reduce the amount Molly eats by 3/4
Hence,
The new quantity that Molly eats =
4 1/2 - 3/4
= 9/2 - 3/4
Find the L.C.M( Lowest Common Multiple) = 4
= (2 × 9) - (3 × 1)/4
= 18 - 3/4
= 15/4
= 3 3/4
Therefore, the new quantity of food that Molly eats = 3 3/4
a) After Molly's food is adjusted will she eat more or less than Roscoe each day?
From Question 10) we are told that Roscoe eats 3 2/3 cups.
Molly's new adjusted amount = 3 3/4 cups
Therefore, Molly eats more than Roscoe each day.
b) how much more or less?
This will be calculated as the difference between Molly new adjusted cups of food and Roscoe's cups of food
= 3 3/4 - 3 2/3
=15/4 - 11/3
Lowest Common Multiple = 12
= 15 × 3 - 11 × 4/12
= 45 - 44/12
= 1/12
Therefore Molly eats more than Roscoe by 1/12 cups
