a recipe includes 1/2 cup of sugar and 1 3/4 cups of flour. susan doubled the recipe by changing the 2 1/2 cups of sugar and 3 3/4 cups of flour.

(a) are susan’s measurements correct? if not, double the original measurements correctly and simplify the answers.

(b) what if susan had to triple the recipe. what would the measurements be? show your work.

(c) describe the process of changing a mixed number into an equivalent improper fraction.

Ok so first lets do A. Her measurements are not correct the actual double is 1 cup of sugar and 3 1/2 cups of flour
Explanation:
2=2/1

Multiply 1/2 by 2/1 you get 1
Change 1 3/4 to an improper fraction and do the same
Multiply 7/4 by 2/1 you get 14/4 which equals 3 1/2

Now B. She would do the same thing but with three instead so

1/2x3/1= 3/2= 1 1/2
7/4x3/1= 21/4= 5 1/4

Now C the process for changing a mixed number into an improper fraction is you multiply the whole number by the denominator and add it to the numerator.
