Write any fraction that is less than 1/8
kotegsom [21]
<span>Sample answers are 1/9, 1/10, etc.

Explanation:
To write a fraction less than 1/8, you can keep the numerator 1 and make the denominator any number greater than 8. 1/8 is the same as one part out of 8. Imagine having many pizzas the same size, but cut into different numbers of pieces. 1 piece out of 8 would be a bigger piece than 1 piece out of 9, out of 10, or anything more than 8.</span>
