0.487 = 487/1000. Since neither 2 nor 5 are factors of 487, this can't be simplified.
48.7% = 487/1000
In the most simple form, the fraction is 29 over 50
The square root of 85 is approximately 9.22. It is an irrational number, meaning it cannot be expressed as a simple fraction. You can also approximate it further as 9.219544457, but typically, rounding to two decimal places is sufficient for most purposes.
In its most simple form, it is simply 1.
It is just like when you simplify a fraction but instead of the word simplifiying it, it is reducing it.
11.5 can be expressed aloud as "eleven and a half" therefore the most obvious units to use to express it as a fraction would be multiples of a half. There are 22 "halfs" in 11 and one more from the .5, so it is most easily expressed as 23/2 or aloud as "23 halves". It should be noted that it could just as easily be expressed with many other denominators (the number on the bottom of a fraction). For example, you could call it 46/4 or "46 fourths" or 92/8 (92 eigths) and so on.
It is not. Simple division is far more helpful.
11.2 = 11 2/10 = 112/10 = 56/5, which is the most simple form of the fraction.
The number 3.14159 can be expressed as a fraction by understanding that it is the decimal representation of the mathematical constant pi, which is the ratio of a circle's circumference to its diameter. Pi is an irrational number, meaning it cannot be expressed as a simple fraction. However, it is commonly approximated as 22/7 in fraction form, which is accurate to a reasonable degree for most practical purposes.
It means that you find a decimal number that has the same value as the fraction - or often a value that is close, since most fractions cannot be expressed exactly with a terminating decimal. Just divide the numerator by the denominator, to get an equivalent decimal.
Yes, negative numbers can most certainly be rational. A rational number is simply a number which can be expressed as a fraction. An example of a negative rational number is: -1/2
The point of oscillation of a simple pendulum is the equilibrium position where the pendulum comes to rest when there is no external force acting on it. It is the bottom-most point of the pendulum's swing where the potential energy is at a minimum and the kinetic energy is at a maximum. This point marks the center of the pendulum's oscillation movement.
