Question

Enter a fraction that is equivalent to 9/10 with a numerator of 81 .

Answer 1

We can write equivalent fractions by making multiplications in both the numerator and the denominator.

That is, to get an equivalent fraction to 9/10, we have to multiply both the 9 and 10 by a number that will give the numerator 81.

81 is the same as 9 times 9.

Thus, if we multiply the fraction by 9 on the numerator and denominator, we will get:

$\frac{9}{10}=\frac{9\times9}{10\times9}=\frac{81}{90}$

So, and equivalent fraction with numerator 81 is 81/90.
