write two decimals that are equivilant to:
0.68
0.9
I think you mean two fractions because the decimal representation is unique (with some exceptions we'll skip for now)
0.68 = 68/100 = 34/50 = 17/25
0.9 = 90/100 = something you can do now
To find a fraction that is equivalent to 0.9, we can use the fact that the fraction represents the ratio of the numerator to the denominator. Since 0.9 can also be written as 9/10 (nine-tenths), we have found one fraction that is equivalent to 0.9.
To find another fraction that is equivalent to 0.9, we can multiply both the numerator and denominator of 9/10 by the same number. For example, if we multiply them by 2, we get 18/20. Therefore, 18/20 is another fraction that is equivalent to 0.9.
So, two fractions that are equivalent to 0.9 are 9/10 and 18/20.
