HELP!!!

Answer 1

Answer:

Givens:

• They have 4c of flour.
• Eliza needs 2 1/3 c of flour.
• Jaime needs 1 3/4 c of flour.

To know if the have enough flour, we just need to sum both amounts, but before that, we need to transform all mixed numbers into fractions

$2\frac{1}{3}= \frac{7}{3}$

$1\frac{3}{4}=\frac{7}{4}$

Now, we sum

$\frac{7}{3}+\frac{7}{4}=\frac{28+21}{12}=\frac{49}{12}\approx 4.08$

Therefore, the just have enough flour to do their recipes, because they need 4.08 c of flour approximately, and they have 4 c of flour.

Answer 2

No you would not have enough flour because if you add those to mixed numbers together you would get 4 and 1/12
