Answer 1

To find which amount of flour is equivalent to $\frac{2}{3}$ of a cup, we can convert it to a different fraction or mixed number.

1. 33 of a cup: This option doesn't match because $33/1=33$, which is not equivalent to $\frac{2}{3}$.

2. 3 thirds of a cup: This is equivalent to 1 cup, since $3/3=1$, which doesn't match.

3. 13 of a cup: This option is not written in proper fraction form, but $13/1=13$, which is not equivalent to $\frac{2}{3}$.

4. 1 third of a cup: This is $\frac{1}{3}$ of a cup, which does not equal $\frac{2}{3}$.

5. 56 of a cup: This option seems to be incorrectly formatted, but $56/1=56$, which is also not equivalent.

6. 5 sixths of a cup: This can be checked by converting $\frac{5}{6}$ into thirds. Multiply by $\frac{2}{2}=\frac{10}{12}$ for sixths:

   • $\frac{5}{6}=\frac{10}{12}$

   • $\frac{2}{3}=\frac{8}{12}$, so they are not equivalent.

7. 46 of a cup: Again, this is improperly formatted but would not equal $\frac{2}{3}$.

The only equivalent amount to $\frac{2}{3}$ of a cup would actually be $\frac{4}{6}$, which unfortunately is not listed among your choices. The closest option that could seem correct without formatting issues typically would be $\frac{5}{6}$ that I approximated with other fractions.

Therefore, none of the provided responses accurately represent $\frac{2}{3}$ of a cup in straightforward terms.
