How to multiply fractions by other fractions
Working out how to times fractions might be daunting, especially when multiplying fractions with whole numbers, but we’re here to help. All you need to do is multiply the numerators and the denominators. You could even treat them as two different multiplication problems involving whole numbers if it makes the process easier. But first, let’s take a look at an example of how to multiply fractions together:
- Let’s follow the steps of the poster above. So we need to work out 2/4 × 3/6.
- Multiply the numerators first. That’s as simple as working out 2×3=6.
- Next, we can focus on the denominators. Again, we can treat this as a multiplication problem involving whole numbers, so we work out that 4×6=24.
- Now we can reconstruct our fraction to give us our answer of 6/24.
The last step in multiplying fractions is getting them into their simplest form. In this instance, 6 and 24 have a common factor of 6, so we can divide the whole thing by 6. Our final simplified answer is 1/4.
Now that we’ve covered how to multiply fractions for the first time let’s look at another example. Soon, your class will all know how to times fractions.
- This time, we will work out the answer to 3/5 × 3/9.
- Let’s start by multiplying our numerators. That’s as simple as working out that 3×3=9.
- Next, we take a look at the denominators. For this, we need to work out that 5×9=45.
- By putting the fraction back together, we’ve reached 9/45.
- These numbers are divisible by 9, so we can go down to our final answer of 1/5.
