Answer 1

Answer:

a).no sugar=1. flour=3 1/2

B). sugar= 1 1/2. Flour= 5 1/4

c) your just simplifying to the smallest possible number

Step-by-step explanation:

1/2 doubled= 1 (1/2+1\2)

1 3/4= 7/4

7/4 doubled= 14/4=3 2/4= 3 1/2(1 1/3+1 1/3)

Answer 2

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.
