Question

Two fractions have a common denominator of 8. What could be the two fractions?

Answer 1

Answer:

There are way too many fractions with a common denominator of 8, because this refers to all fractions which denominator is multiple of 8.

For example, two fractions that fulfil this characteristic can be

$\frac{4}{16} \ or \ \frac{10}{40} \ or \ \frac{3}{24}$

All these fractions have a common denominator of 8, because they can be divide by 8 actually.

If you have specific choices (which you didn't post), you need to choose the options which denominator can be divide by 8. If your answer is in a general context, there you can choose two fractions that fulfil the characteristic we explained before.

Answer 2

4/16
or
6/32

mainly because denominators can be divided by 8
