Multiplying fractions

A fraction is a part the a whole. In the critical lesson, friend learned exactly how to add and subtract fractions. However that’s no the only kind of mathematics you have the right to do v fractions. There space times once it will certainly be useful to main point fractions too.

You are watching: 1 times 1/3

Click v the slideshow to learn exactly how to create a multiplication difficulty with fractions.

*

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

*

But her doctor just told you the you require to rtastecraftedmcd.comced down your coffee drinking by half.

*

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

*

This might not look prefer a multiplication problem. But when friend see the word of v fractions, it way you must multiply.

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

*

Now our example is all set to be solved.

*

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

*

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

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

*

So once we multiply 1/2 time 2/4...our answer will certainly be smaller sized than 2/4.

*

Here's one more example. Let's say you have actually 3/5 the a cup of cacao filling.

*

You want to put an same amount of filling in each of these 4 cupcakes.

*

You might say that you desire to put 1/4 the 3/5 the a cup of filling in each cupcake.

*

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

*

And currently our fractions are ready to be multiplied.

Try This!

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

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


*

Note: back our example says the exactly answer is 2/3 x 1/2, remember, v multiplying bespeak does not matter. 1/2 x 2/3 would also be correct.

Solving multiplication difficulties with fractions

Now that we know just how to collection up multiplication difficulties with fractions, let's exercise solving a few. If you feeling comfortable multiplying totality numbers, you're all set to main point fractions.

Click with slideshow to learn how to multiply two fractions.

*

Let's main point to discover 1/2 the 7/10.

*

Just choose we did earlier, we'll change the word of v a multiplication sign. Now we're prepared to multiply.

*

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

*

1 times 7 equates to 7, so we'll create 7 come the right of the numerators.

When us added fractions, the denominators continued to be the same. But when we multiply, the denominators obtain multiplied too.
