HELP!!!

Answer 1

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(1)/(3)= (7)/(3)`

`1(3)/(4)=(7)/(4)`

Now, we sum

`(7)/(3)+(7)/(4)=(28+21)/(12)=(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.
