Multiplying fractions

A portion is a part the a whole. In the last lesson, girlfriend learned exactly how to add and subtract fractions. But that’s no the just kind of math you can do v fractions. There are times when it will be advantageous to main point fractions too.

Let's collection up a multiplication example with fractions. Suppose you drink 2/4 that a pot that coffee every morning.

*

But your doctor just told you the you need to rgimpppa.orgced down her coffee drinking by half.

*

Now you require to figure out just how much 1/2 the 2/4 the a pot the coffee is.

*

This might not look like a multiplication problem. However when you see the word of through fractions, it way you need to multiply.

To collection up the example, we'll just replace the word of v a multiplication sign.

*

Now our example is all set to it is in solved.

*

Unlike consistent multiplication, which offers you a larger number...

*

Unlike consistent multiplication, which offers you a larger number...multiplying fractions will certainly usually give you a smaller number.

So once we main point 1/2 times 2/4...

*

So as soon as we main point 1/2 time 2/4...our answer will certainly be smaller sized than 2/4.

*

Here's one more example. Let's to speak you have actually 3/5 of a cup of coco filling.

*

You want to put an equal amount of filling in every of these 4 cupcakes.

*

You can say the you desire to put 1/4 the 3/5 of a cup of filling in every cupcake.

*

Just prefer we go before, we'll readjust the native of right into a multiplication sign.

*

And now our fractions are ready to it is in multiplied.

Try This!

Try setting up the multiplication problem below. Don't worry around solving the yet!

A cooking recipes calls for 2/3 that a cup that milk. You desire to cut the recipe in half.


*

Note: although our example says the exactly answer is 2/3 x 1/2, remember, v multiplying order does no matter. 1/2 x 2/3 would also be correct.

Solving multiplication problems with fractions

Now that us know how to collection up multiplication troubles with fractions, let's exercise solving a few. If you feel comfortable multiplying whole numbers, you're all set to multiply fractions.

Click through slideshow to learn how to multiply 2 fractions.

*

Let's multiply to find 1/2 that 7/10.

*

Just like we go earlier, we'll change the native of through a multiplication sign. Currently we're prepared to multiply.

*

First, we'll multiply the numerators: 1 and also 7.

*

1 times 7 equals 7, so we'll compose 7 come the appropriate of the numerators.

When us added fractions, the denominators stayed the same. Yet when us multiply, the denominators gain multiplied too.
