Question

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?

Answer 1

19/6 cups

Step-by-step explanation:

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

`3(1)/(2)=(3\cdot2+1)/(2)=(7)/(2)`

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

`(7)/(2)-(1)/(3)=(7\cdot3-2\cdot1)/(2\cdot3)=(21-2)/(6)=(19)/(6)`

Therefore, she needs 19/6 cups more
