Question 3 1 Marge is making a chocolate cake to surprise the best nend. She needs 3 1/2cups of four but she only has 1/3cup. How much more flour does she need?

Sagot :

Answer:

19/6 cups

Explanation:

First, we need to transform the mixed number into a fraction as:

[tex]3\frac{1}{2}=\frac{3\cdot2+1}{2}=\frac{7}{2}[/tex]

Now, we need to subtract 1/3 from 7/2, so:

[tex]\frac{7}{2}-\frac{1}{3}=\frac{7\cdot3-2\cdot1}{2\cdot3}=\frac{21-2}{6}=\frac{19}{6}[/tex]

Therefore, she needs 19/6 cups more
