Not sure if you guys are doing the same thing as I am right now but this is how we would answer it! I hope it helps.
you can write 0.115 as a fraction in the
following way:
Let x = 0.115
Then 10x = 1.15
And 100x = 11.5
Subtracting the first equation from the second, we get:
100x - 10x = 11.5 - 1.15
90x = 10.35
Dividing both sides by 90, we get:
× = 10.35/90
Simplifying this fraction by dividing both the numerator and the denominator by 5, we get:
× = 2.07/18
Therefore, 0.115 is equal to the fraction 2.07/18.
