1.3 J) Multiplying Fractions – Part 1
When we are multiplying mixed numbers, we should convert the mixed numbers into improper fractions, and then multiply across in the same way as above. There is an example of where this is the case in the next section.
Complete the calculation below.
To answer this question, we multiply straight across; we multiply the two numerators to get the numerator of the answer, and we multiply the two denominators to obtain the denominator of the answer.
The next step is to simplify the answer, which we do by dividing the numerator and the denominator by the highest common factor between the numerator and the denominator. The highest common factor between 6 and 20 is 2. Therefore, we divide the numerator and denominator by 2.
The fraction above is not an improper fraction, which means that there is no need to convert it into a mixed number (an improper fraction is where the numerator is greater than the denominator).
Therefore, the answer is 3/10.
Complete the calculation below.
To answer this question, we can just multiply across.
We now need to simplify. The highest common factor between 18 and 88 is 2, so we divide the numerator and the denominator by 2.
Therefore, the answer is 9/44.
