Question

Garnet has a container with 4 1/2 cups of flour in it. She can make one dozen muffins with 2 1/2 cups of flour. How many dozens of muffins can Garnet make with the flour she has?

Answer 1

Answer:

1.8 or 9/5

Step-by-step explanation:

4$\frac{1}{2}$ ÷ $2\frac{1}{2}$

Change into improper fractions

$\frac{9}{2}$÷$\frac{5}{2\\}$

Flip the second fraction and then multiply

$\frac{9}{2}$×$\frac{2}{5}$=$\frac{18}{10}$

18/10 is 1.8 as a decimal and 9/5 simplified

Answer 2

Answer: 1-4/5 dozens of muffins.

Step-by-step explanation;

Step One. Turn the fractions into decimals to make it easier; 4-1/2 will be 4.5 and 2-1/2 will be 2.5.

Step Two. Apply the rule of three, using the variable x to represent the number of muffins Garnet can make; 2.5/1 = 4.5/x.

Step Three. Solve for x by cross multiplying; x = 1.8. So Garnet can make 1.8 dozens of muffins with 4.5 cups of flour.

Step Four. Convert the decimal into a fraction; 1.8 in a fraction form is 9/5, or 1-4/5.
