Which one is bigger and how do you know? 1/8 or 1/9 (Give at least two strategies) i

scoray [572]

Answer:

1/8 is the bigger fraction

Step-by-step explanation:

When comparing fractions with different denominators, and the numerator is one, like 1/8. The one with the smaller number for the denominator is greater.

You could also compare them by finding common denominators, so for 1/8 and 1/9, a common denominator would be /63. So you would take $\frac{1}{8}$ and multiply that by $\frac{9}{9}$ . You would then get $\frac{9}{63}$ . When you take $\frac{1}{9}$ times $\frac{8}{8}$ you get $\frac{8}{63}$ . So when comparing you can see that 1/8 is greater than 1/9.
