There is 3/4 pound of cream in a containwr. Julian will use 3/8 pound of cream to make crème brûlée. What fraction of a pound of
Ksivusya [100]

Answer:

\frac{3}{8}\ pound of cream will remain in the container.

Step-by-step explanation:

Given:

Amount of cream in the container = \frac{3}{4}\ pound

Amount of cream used to make crème brûlée = \frac{3}{8}\ pound

We need to find the amount of cream remain in the container.

Solution:

Now we can say that;

the amount of cream remain in the container is equal to Amount of cream in the container minus Amount of cream used to make crème brûlée.

framing in equation form we get;

amount of cream remain in the container = \frac{3}{4}-\frac{3}{8}

Now we will make the denominator common using LCM we get;

amount of cream remain in the container = \frac{3\times2}{4\times2}-\frac{3\times1}{8\times1}= \frac{6}{8}-\frac{3}{8}

Now denominators are common so we will solve the numerators.

amount of cream remain in the container = \frac{6-3}{8}=\frac{3}{8}\ pound

Hence \frac{3}{8}\ pound of cream will remain in the container.
