The number 1
/4 is a fraction, and fractions are ratios, and ratios are ratio-nal numbers!
Explanation:
Every fraction is comparing one number to another. So, for example, the number 2
/5 is comparing the number 2 with the number 5. In this case, the fraction is saying that 2 is the fractional part and 5 is the whole part. So if a pizza was cut into 5 equal slices, and I ate 2 of those slices, I would have eaten
2
/5 of the pizza.
The ratio is a different way of saying exactly the same thing. Instead of writing 2/5, we could write 2:5, which is a ratio comparing 2 to 5. Therefore, every rational number is a number that can be expressed as a quotient a/b of two integers. The integer a is called the numerator, and the integer b is called the denominator and cannot be zero (0).

, however, it is not the sine of the angle to the power of -1.
