Juvi is baking oatmeal raisin cookies and fudge brownies! To make 4 batches of brownies, Juvi needs 2/3 of a cup of sugar. She a

dsp73

We can add the fractions together to compare with how much sugar she needs.

$\frac{1}{2}+\frac{2}{5}=\frac{5}{10}+\frac{4}{5}=\frac{9}{10}$

So Juvi has $\frac{9}{10}$ cups of sugar.

She needs $\frac{2}{3}$ cups, so let's make the denominators the same and compare.

$\frac{2}{3}=\frac{20}{30}$

$\frac{9}{10}=\frac{27}{30}$

Since $\frac{27}{30}$ > $\frac{20}{30}$ , she has enough sugar to make 4 batches of brownies.

Hope this helps.

頑張って!
