Question

A recipe includes 1/2 cup of sugar and 1 3/4 cups of flour. Susan doubled the recipe by changing the measurements to 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) Describe the process of converting a mixed number into an equivalent improper fraction.

Answer 1

A.not they are not correct,

the correct "doubled" way would be

1 cup of sugar and 1 2/4 cup of flour (1 1/2 simplified)

B.the process of converting a mixed number into a equivalent improper fraction is to first add the "bottom" number to the top, then take away the whole number.

Answer 2

No, Susan is wrong because when you double 1/2 it becomes 1 cup of sugar and doubling 3/4 becomes 2 and 2/4, simplified version being 2 1/2 or 2.5
