How do you multiply fractions?
vazorg [7]

It's easier then you'd expect it to be. There's no need to convert the fractions so that they all have a common denominator like you'd have to do when adding or subtracting fractions.

Let's take a look at something really simple.

\frac{1}{4} *\frac{2}{6}

We can multiply the numerators together so 1*2. We can multiply 4*6 to get the denominator.

This means that our fraction becomes \frac{2}{24}.

Now I'm assuming since you already know how to add fractions you'll know how to simply fractions. So 2/24 will become 1/12.

Try searching it up on Khan Academy to grasp the topic better!

Answer is 20. -4 x 1 is -4 so it doesn’t change. -4 -8 makes it -4 + 8 as there’s two negatives. 9 divided by 3 is 3. So it’s -4 +8 x 3. 8x3 is 24. So -4 + 24 = 20. Therefore final answer is 20

ValentinkaMS [17]

Answer:

\frac{22}{15}

Step-by-step explanation:

The computation of the Julie drink altogether is as follows:

= \frac{4}{5} + \frac{2}{3}\\\\= \frac{12 + 10}{15}  \\\\= \frac{22}{15}

We simply added the total liter of water that she took before going jogging and after her jog
